Are you looking for hinges that can come apart, but are secure when assembled together?  Guden Un-Hinges have retractable pins that allow for the hinge leaves to separate, and when the spring-loaded pins are allowed to extend, they lock in place to hold the hinge together.  There are several versions, with and without holes, and with one pin or two pins. They're also available in zinc plated steel and stainless steel.  Click here for the full line of options. 

What are the parts that make up a Catch and Strike set? Sometimes also referred to as Draw Pull Catches, they're comprised of  A - The main catch part,  B -The strike part and C - the loop  that is attached to the catch and fits over the strike to lock the two pieces together.   Guden has many varieties and styles available from stock in steel, plated steel and stainless steel.  There are even versions that accept a lock, and springs to create even more tension for the closure.  Click here for the full line of sizes

Are you trying to dimension where the holes are going to be our custom hinge?   First, almost always, the hole dimensioning is taken to and from the center point of your hole.  For a single hole, you need two dimensions.  In the picture, Dimension A is from the end of the hinge perpendicular to the pin to the center of the hole.  Dimension B will be the distance from the edge of the leaf across the pin to the center of the hole.   If you have multiple holes, you can specify Dimension C is from the center of the first hole to the center of the next hole.  If the hole spacing is going to be the same for each hole, it is common to call it out as center-to-center and just call out the number of times it occurs.  For 7 holes, there would be 6 center-to-centers.  For more assistance, see our custom hinge selection form to choose your hinge style, and then holes.

What exactly are extruded aluminum hinges?  Unlike regular rolled hinges where the flat sheet of metal is curled around the pin, extruded hinges are one solid piece of metal.  Each leaf is a separate solid piece.  The knuckles are then milled out and a hole drilled through the entire length of the hinge.  The two halves are fitted together, and pin slid thru the hole to make the hinge assembly.  This type of construction allows for much closer tolerances for play in the hinge, as well as increased strength in a lightweight material.  Commercial versions of this hinge are available, but the most popular would be the MS20001 series for aerospace applications.  Check out our entire line of extruded hinges here.

The answer is Yes! Temperature can be a very big factor in how a gas spring operates in an application. The gas spring cylinder is filled with nitrogen gas and the higher the temperature, the faster the gas molecules move. The molecules moving faster, causes the volume of gas and pressure to increase which makes the gas spring stronger.

Are you looking for a more stylish appearance for your hinge knuckles?  Is your hinge length not a multiple of the knuckle length?  Then you may want to look at having the hinge cut with balanced ends.  Making your end knuckles smaller than the center knuckles can sometimes make your hinge look less utilitarian.  If you want to not have one end knuckle a different size than all the others, we can split the end knuckles and have each end be the same length to balance things out.  Check out this customization as well as many others here on our hinge customization page.

Are you looking for custom hinge leaves?  Guden can supply unequal leaves, bends, holes slots, and an assortment of customizations to any hinge leaf or leaves.   We can even combine features as you see on the hinge in this picture that has a custom width and a bend.  Check out all the custom operations available and submit your design for quotation on our easy-to-use custom hinge form. 

Leaf swaging is the process of changing the plane of one or both of the hinge leaves.  The operation moves the leaf or leaves in the direction of the pin side of the leaves.  This altering of the leaf planes helps adjust for mounting on different level surfaces or to adjust the gap left between the two leaves.  The different styles as shown are: one leaf half swaged, both leaves half swaged, one leaf full swaged, and swage to resemble reverse assembly.  Each moves the leaf or leaves to a set position.  You can read more information here or contact a Guden Representative to discuss your application needs.

Now more than ever, many of us are realizing just how important the on-time deliveries and stock levels of our suppliers have become. As always, Guden remains committed to doing everything possible to ensure that you continue to have the parts you need, when you need them. Here are just some of the options we can offer:

Guden door pulls come in many shapes and sizes.  They are available with holes for mounting with fasteners and without holes for welding.  Many applications can use our zinc-plated versions, and we also supply them in stainless steel or plain steel too if you should need to apply your own finish, as seen in this picture. Check out this door pull, as well as the entire line of Guden pulls and handles here.

There are many ways to cut a hinge, but an unbalanced shear can also satisfy two requirements. This type of cut shears through the knuckle instead of between two knuckles. For example, on a hinge with .50” knuckles, the length would be 10.30” instead of 10.00” or 10.50”. When the shear comes down, it will crush the knuckle a bit and deform it. This will end up trapping the pin and acts as its own form of pin retention, so it doesn't fall out of the hinge saving an extra operation of staking or welding the pin. So, if a slightly deformed knuckle doesn't bother your application, this would be a cheaper alternative to a saw cut which will be highlighted in a future post. You can also check out a little more on Unbalanced Shears here.

For applications where one gas spring end is higher than the other for the majority of it's at rest position, it is recommended to have the tube end higher than the rod.  I noticed right away on this food truck awning that their gas springs were mounted incorrectly.  In this application the rod is in the up position.  This allows the lubrication oil in the tube all flow to the bottom, and not surround the protective seal for where the rod enters the tube.  If the seal dries out, more gas pressure can possibly escape shortening the lifespan of your gas spring.  It also doesn't allow the rod to move through the oil which can help with adding a dampening effect for when the unit is compressing.  If at all possible, mount your gas spring with the tube higher than the rod for a longer life and better workability.

Does your application require your hinge leaves to be more than just bent at an angle?  Guden has access to many manufacturing and tooling processes that just about any design you can dream up can be possible.  How about mounting to a rounded surface?  This hinge has curved leaves to suit just that need.  Just give us the radius dimensions and we can provide the custom hinge just as you need it.  Simply use our custom hinge selection tool to submit your application requirements.

There are lots of hardware choices to keep a door closed, but there are some even better choices to also allow for opening the door. Guden Spring Latch Hinges and Guden Slam Latches both allow the door to be held in the closed position with a spring-loaded pin. Their bent pins can then be retracted to allow the door to be opened. But that's where the similarities end.

Are you looking for a decorative knob for your application? Guden has a selection of stock knobs in several materials and finishes. Some have a rounded sphere type end like in this picture and are made of brass and are available in no finish or a chrome plating. We also have styles that have a flat grip and are supplied in a zinc die-cast material. All of our knobs are supplied with tapped holes for an easy mounting. Check out the entire line here.

The pin and barrel dimension for a hinge can sometimes be a mistakenly called out, which at times can be confusing.  They are related, but they are two separate dimensions as shown in this picture.  The actual pin is one diameter, and then the barrel dimension (A) is basically the pin diameter (B) plus two times the material thickness.  It's not equal to it, just due to the space required for the pin to move within the hinge, but for barrel dimension purposes, it will be within reasonable tolerances on most drawings. Sometimes people will confuse the two and say the barrel dimension instead of the actual pin dimension, but you can sometimes tell something is wrong because the "pin" dimension turns out to be three times or more the material thickness and that's not the norm. Check out more on the anatomy of a hinge here. 

Many applications just require a piece of hardware to grip so someone can open a door or lid. Guden threaded Rod Pulls are an easy way to meet that need. They're available in a curved U shape design, in an assortment of lengths and heights. Aside from making sure the size is correct, you also have to make sure you're using the proper screws, or you will end up with the situation seen in the picture. The ends of the rod pull are threaded to accept a screw, so it's important to use the proper threading as well as the proper length. Not quite sure why, but this size screw seems way off for this application, so my guess is that they wanted it this way so someone could fit more than just their fingers through the handle opening, or someone with a very very big hand opens this particular door. Guden Rod and Wire pulls are available in brass, stainless steel and aluminum and supplied in several different stock finishes. Check out the entire line here.

Does your hinge require more than just holes or slots? Maybe you're looking to place a hinge around something that doesn't allow your hinge leaf to lay flat?  We can easily supply your hinge with cut outs or any number of shapes to achieve this. Guden has access to all the latest laser cutting technologies so just about any perforation shape or cut out is possible.  Simply send us your dimensioned print for quotation and we'll gladly supply it as a custom run. See our custom hinge site for assistance in starting this process for cut outs and any number of specialty operations you require for your hinge.

Are you looking for a hinge that has strength, beauty and can also be concealed from view? Guden has your answer with Soss Invisible Hinges! We stock a large selection of sizes and styles to fit either metal or wood applications and one is sure to meet your requirements. Each hinge has an interwoven finger-like design for the hinging points and is uniquely crafted in either plated steel or heavy duty zinc alloy. Both materials can be supplied in a satin chrome, satin brass, satin nickel or black e-coat finish with other finishes also available. And for even more corrosion resistance and durability, they are also available in a 316 stainless steel material with a satin finish.

Most of you have probably looked under a folding table and seen how the legs are connected. Or maybe you've even had to collapse one down or set a table up at a backyard party or family event.  This folding piece of hardware is a table leg brace.  There is usually a safety button mechanism to keep it in the straight position, and when pressed, it allows for the unit to fold down so the table leg can collapse down under the table.  I found this more non-standard application use of one on this stepladder, but the concept it still the same.  You straighten the brace to lock it in place, then depress the safety lock button to refold it.  Guden also offers smaller versions as lid and fall supports, with a built-in bump over style locking mechanism that requires pressure for folding instead of a push button. Perfect for lower weight applications. Check out all the styles of supports and braces Guden has to offer here.  

You've all seen holes that have a slight angle to them so a flathead screw can fit snugly and lay flat into the surface of your hinge. These are countersunk holes. This type of hole is used when you don't want to see a round head of a screw above the surface.  They're also used to allow the hinge leaves to lay flat against each other when closed so the screw heads aren't in the way.

Are you looking for a hinge that can be mounted hidden from view?  Guden offers a selection of hinges for just this type of application.  Our concealed hinges, like this one shown, allow for a door to be flush to the panel its covering, without any visible pin or hinge leaves.  This unique multi-pin construction moves the door up, out and over the frame opening so there is total access to whatever is underneath. Check out our entire line of concealed hinges, including this style towards the bottom of the page.

Most stock hinges have two leaves that lay flat for attaching to another flat surface. But what do you do when you need to mount to two perpendicular surfaces or two surfaces not in the same plane?  Thats when leaf bending comes into play.  Almost any hinge leaf can have one or more bends in it, and the bend doesn't have to just be a 90 degree bend like you see on this slip joint hinge leaf.  Guden has the capability to do just about any bend angle you need to fit your application.  Just submit your drawing or requirements here on our custom product form and we'll get a quotation back to you. 

Are you in need of a hinge that allows you to lift off your door like this wall locker box? Guden carries a large selection of these types of hinges. Commonly known as Lift-Off, Slip Joint, Loose Joint and Take-Apart hinges, these two-piece sets let you rotate your door open when connected together. You are able to easily remove the door by separating the hinge halves from each other.  They are available in Right Hand and Left Hand versions and you can watch our video for more information on handing. Click here to see our full line of sizes available in all the popular materials.

Gas springs are filled with nitrogen and when at rest, that pressurized nitrogen keeps pushing the rod out of the tube. The pressure of gas springs can range from five pounds up to several hundred pounds.  While most people can compress a lower pound pressure spring by hand, you should never try to compress a gas spring to install it.  You should always manually raise your lid or cover to the designed open angle and then connect your gas spring to the mounting points. This is your safest way of installing it and allowing the weight of the cover to compress the spring.  If you need assistance picking the right gas spring and mounting points to use, we're here to help!  Let Guden help guide you to the optimal solution based on your application parameters by using our gas spring selector process. 

Two-piece draw pull catch and strike sets are a great way of securing a door, cover or lid in place as soon in this picture.  The catch has a ring of metal that is pulled down and over the strike portion and then clamped down tight to "draw" the door to the frame. They're available from stock in several sizes, and in steel, zinc plated steel and stainless steel materials. We also offer them with holes or without. If you're looking for an even tighter fit, you can check out our compression spring catches that are assembled with torsion springs and for more security, we also can supply ones with an arm extension perforated to accept a lock or cable tie to ensure that the catch isn't opened. MS18015 spec government catches are also available from stock.  Check out the entire offering of Guden catch and strike sets here.

Spring loaded hinges are available in two styles; spring-loaded-to-open and spring-loaded-to-close. They are stocked in plain steel, zinc plated steel and stainless steel. You can choose between spring hinges with or without holes. The action words Open and Close should not necessarily be confused with how the door will move because that is dependent on how the hinge is mounted.

Spring-Loaded-To-Open Hinges

have the torsion spring installed to push the hinge leaves away from each other to the open position of the hinge.

Spring-Loaded-To-Close Hinges

have the torsion spring installed to push the hinge leaves towards each other to the closed position of the hinge.

You can see this explained in our video presentation here.

It's important to design your product with the action of the spring pushing on the hinge leaves in mind. Depending on which side of the leaves are being attached to your door and frame will determine which type of spring hinge you will require.

Normally it's best to try to mount your door or frame surface to the side of the leaf that is free of the spring leg. If you do need to mount to the spring leg side, Guden can supply the leaf with an emboss or channel for the spring leg to lay in so it is not crushed during the mounting process or impeded from having good motion and strength.

Guden spring hinges are available in stock in many sizes and strengths and can also be custom made to fit your exact requirements. Check out the full line here.

Slots, also known as obrounds or ovals, need to have a dimension to identify their size just like any other perforation. When dimensioning holes, all is needed is the diameter, but how does one call out a slot size?  A slot is really just an elongated hole, so first you'd need to know the hole diameter. Then you can either call out the dimension from center-to-center on the holes making up the ends of the slot or just call out the overall length. Slots are typically made with punching dies. It is helpful if you can use a size that we already have a punch for, but we can certainly offer any size you want with a tooling charge. Click here for more information on slotted holes.

Ever wonder why sometimes you see a different size gaps around the knuckles of a hinge?  The gap is the paint clearance for the hinge and is set at a standard dimension for each hinge size to give enough space for painting. If the painting is too thick, the knuckles will touch the surface of the barrel when the hinge rotates and some of the paint may scrape off.  Definitely not something you want to happen. The hinge in this picture is a great example of a custom paint clearance as it's a very large gap.  Click here for a little more information on this topic.

The pin of the hinge is normally run loose enough for the hinge to turn, but tight enough so that it doesn't just fall out either.  In some applications, the pin can start to work itself out over time and start to stick out the end of the hinge.  So what can you do about it?  There are several ways to prevent it and one of the easiest and quickest ways to retain the pin is to have it staked.  Staking is the process of indenting the hinge knuckle so it presses against the pin as you can see in this picture. This process does prevent the pin from moving, but you can still drive the pin out with a bit of effort just in case you need to take the door off.  You can have one stake or more depending on how difficult you'd like it to be to drive the pin out.  Check out more information on staking and other pin retentions here.

Some applications need more than just 1 pin and two leaves to allow for a door to swing even wider than usual, or to fold around something.  In some cases, they are mounted so that two different panels can move on the same mounting point like the application shown.  We even have the ability to join multiple hinge leaves with any number of pins to, in theory, even make an entire wall of hinge leaves if you so desire.  Do you have an application that sounds like this?  Submit your custom hinge specifications to us on the Guden Custom Hinge Form here.

Having trouble deciding on how to mount your hinge? There are a number of different ways of mounting your hinge depending on your requirements. Here are the three most common methods:

Welding

— If your application is a metal hinge on a metal frame and door, you can choose to mount the hinge by welding. For a fillet weld, as shown here or for a spot weld, you won't need to have holes in your hinge or on the mounting surfaces. Some might not consider welding as aesthetically pleasing or desirable if the application is visible or more decorative but you can have holes punched in the leaf and do a plug weld which is a neater look. Welding is a very secure mounting and you will have a great deal of trouble if you need to remove the door.

Standard Fasteners

— Putting holes or slots in your hinge, door and frame will allow for using separate fasteners like bolts or screws to mount your hinge. You do need to take care about lining up the holes and using the right size hardware. A nut may be required if your screw is being used in a non-threaded hole. Most standard fasteners also allow for easy removal or you can also choose riveting or non-removable type screws for more security against tampering.

Self-Clinching Fasteners

— A popular brand of built-in fasteners is from Penn Engineering Manufacturing or more commonly known as PEM. There are also many other brands of self-clinching fasteners that can be supplied already installed on your hinge. Both threaded studs and threaded inserts are available in hundreds of sizes. Using these will reduce the amount of extra hardware you need to worry about and can speed up the mounting process.


Almost all Guden hinges are available from stock without holes for welding applications, with many also available with a standard hole patterns to use with standard fasteners. If one of our stock patterns doesn't fit your application or you'd like your hinges supplied with self clinching fasteners, Guden can easily supply them to your exact specifications as a custom run. Check out our entire line of hinges, and use our custom hinge form to submit your application for quotation.

Larger weights and high security applications often require heavy duty hinges and Guden has plenty of them right on shelf for immediate shipment. Take for instance the outdoor ATM unit shown here.  You would definitely want a thickness and pin that can withstand some tampering and abuse.  Available in steel, stainless and aluminum and many are in stock in thicknesses of 14 gauge all the way up to 7 gauge, with even heavier gauges supplied on a custom run.  Choose from continuous lengths, butt hinges and spring latch hinges too.  Check out the entire line here.

It's their gleaming shiny finish that gets Guden strap and T hinges noticed! Each hinge has a smaller leaf for the frame and a longer leaf to support any large door or cover. They're supplied in stainless steel for outdoor durability and polished for a decorative look as you can see in this picture. Check out all the available Guden sizes and styles here.

Most standard hinges have leaves that are the same length but what about applications that would benefit from one leaf being a different size than the other?  That's when a hinge with unequal leaves would be needed like shown here.  Just specify what hinge leaf dimensions you require and Guden can custom run the exact size that you need.  Click here to submit your specifications on our custom hinge form.

Don't be a square,  or a rectangle too for that matter. Tired of all the standard hinge shapes?  Guden has your answer! Laser cutting has now allowed for almost any shape or cut-out imaginable on your hinge.  Just look at the intricate curves and holes on this fancy gate hinge.  Challenge Guden with your most creative or decorative design by quickly and easily submitting your specification drawing here

Searching for hardware to keep a door or lid shut is easy. And finding a product that allows for a quick opening is just as simple! Check out the Guden spring latch line. Each is assembled with a pin that is spring-loaded to keep it in the extended position. One end of the pin is bent for gripping to retract the pin so you can release the lid or cover. We offer many different sizes, in steel, stainless and plated steel too. Some are even available with a rubber tip for a better grip and others have a hold-back feature to keep the pin in the retracted position. Check out the entire line of Guden spring latches here.

Choosing the wrong type of handle or pull for your application could just have you end up with this situation!  Many factors should be reviewed before selecting the handle. What strength does it need. Does mounting with screws from the front make better sense than a tapped hole rod pull type?  Maybe welding the handle to the surface?  With so many choices, it's no wonder that people sometimes pick the wrong type.  Check out all the handles and pulls that Guden has to offer here.

Continuous hinges are supplied in several different knuckle length sizes. From .25" knuckles to .50", .625 , the rare .75" and then 1" and 2" knuckles for most of your more heavy duty hinges.  Our stock hinges are always supplied in lengths divisible by the knuckle length, but you can also get them supplied in the length of your choice, or cut them down in your own facility. 

Gas springs without black nitrided rods?  How 2000's! " Detective H.A, thought to himself as he spied the lid on this box.  He certainly didn't need any more clues as to what was assisting and holding this cover open on its own as the gleaming chrome rod was very easy to spot. He knew black nitrided rods were so much more aesthetically pleasing to the eye, and let the gas spring almost disappear from view.  H.A. even knew how much more environmentally friendly black nitrided rods are over chrome rods.  His next assignment was going to be to finding the designer of this box to show him his choices.  Are you looking for gas springs with black nitrided  rods?  Click here to see the huge selection.

A great looking rod pull is the perfect addition to any door. I spied this stainless steel handle on this glass door and it made me think of the several ways a handle would mount in an application. Is it a surface mount where the handle is welded ? Is it screwed down from the front of the door?
Or maybe are the screws hidden and it's mounted through threaded holes in the rod pull like the application shown here. You can find all the different Guden handle and rod pull styles here: https://www.guden.com/control/handles-pulls

Selecting the product that works perfectly in your application sometimes requires reviewing different items that have very similar functions, but have different attributes to offer. Gas springs and spring hinges are two of those items. While they are two very different products, they both provide motion and each can hold a lid, door or cover in a position So which one is right for your application?

Gas Spring and Spring Hinge Applications

Gas springs can be used in any application that has a door, lid or cover that requires an assist in opening and holding in the open position. Vehicle doors, cabinetry, equipment hoods, trunk lids, and enclosure covers are just a few examples for where they can be found. While the typical application is on a horizontal lid, they can also be used on a vertical door for a side to side motion. Spring hinges can also be used in any application that has a door, lid or cover that needs to be pushed open, or held closed without assistance. These doors are typically smaller in size and weight as the force is limited to the strength of the torsion spring. Most often used in a vertical mount door, they can be used on a horizontal door as well.

Corrosion resistance is a concern for many hinge applications and many will opt for stainless steel or aluminum materials as they will resist rust adequately in most situations. Another option is plastic. Hinges made of plastic nylon resist corrosion and are also lightweight, non-conductive and decorative. Of course they aren't as strong and sturdy as metal, but they can support many medium and light duty applications. Check out all the standard plastic hinge sizes Guden has to offer HERE

Detective H.A. Wasn't quite sure what to make of this hinge he spied underneath an adjustable seat on a plane.  At first glance, it looked like a regular hinge but with further investigation, he saw the leaves weren't in the same plane as they usually would be! What could cause this, he pondered, as he checked his notes on leaf orientations. With the leaves assembled reverse of what they normally would be, each leaf was on opposite sides of the pin instead of the same side. Why would someone do this? To allow for more rotation of the hinge? Or maybe they needed the offset between the leaves for the mounting? It was a bit of a mystery that might need more exploring.

No matter where you are, you should always keep a look out for hinges!  Sometimes they're in a hidden spot, but sometimes, like this cover on a iced beverages cart, you'll find some right out in the open.  For some reason, this designer wanted the hinge to mount on the top surface and the inside surface as I could see from the extra wide hinge bent leaves.  Maybe he could have saved a little money by just using a standard slip joint on the side surfaces, but this arrangement seemed to pull the lid slightly off to the side which led me to believe maybe they didn't want someone catching themselves or anything else on it? One thing's for sure,  Guden can create a custom slip joint hinge like this, or to your specifications easily!  Hinge Customizations | Glossary | Guden Custom Hinges

Most people know hinges to have standard square corners, but a corner doesn't have to just be a corner. Here are two common custom operations that can be done to a regular corner.  1. Clipped Corners give you a triangular cut out while 2. Radius Corners give you a rounded feature.  Both help eliminate something catching or snagging on the pointy hinge corner and add a little bit of a decorative touch. You can read more information on these features here.

It was late evening at a roadside diner when Detective H.A. had an odd feeling.  He scoped around a bit, and then spotted it.  Following a trail of paper towel scraps, they brought him to this horrible sight -a hinge with a missing pin. A former shell of itself, all that remained of the hinge was just a half leaf left lifeless.  H.A. knew very well that without the proper pin retention, a pin can be pulled, pushed, or even dragged out of a hinge, but who could have let this happen?  Was it staked? Had there been a crimped end? Maybe signs of a spun end or two? He quickly referred to his notes on Pin Retention and found no evidence that anyone had taken steps to prevent this hinge tragedy.  If only they had viewed the Pin Retention Case Video, he thought, this situation could have been avoided. 

Paint clearance is the normal gap left between the knuckle and the barrel of the hinge when it is made. It's used as a guideline for the thickness of the painting or plating applied to the hinge surface.  Most professional finishers will ensure that they are within the guideline, but if they don't, the error is usually quite obvious.  See here for more information: paint clearance | Anatomy of Hinges | Glossary (guden.com)

Gas Spring Definition:

(noun) A motion control device that offers controlled raising of an object with the use of gas pressure.

Gas Spring Synonyms

Gas Springs can be called many different things. There can sometimes be confusion about what a gas spring is due to the multitude of different names. Gas springs can be called gas struts, gas spring lifts, gas props, gas shocks and more.

The Difference between a Gas Spring and Damper

People looking for Gas Springs tend to either want a gas spring or a damper. Dampers assist in closing at a controlled speed. Dampers reduce speed with no added force. For more information on our dampers, please see our entire selection of extension and compression dampers.

Guden has a wide selection of Gas Springs

Guden gas springs are the perfect product to help control the motion of your lid, door or cover. Each pair is capable of helping keep the lid in the closed position, aid in lifting, and then holding the lid in the open position. Each gas spring is pressurized with nitrogen gas and contains a small amount of lubricating oil within the cylinder.

Different Types of Guden Gas Springs

• Standard Gas Springs
• Locking Gas Springs
• Friction Stop Gas Springs
• Self Centering Gas Springs
• Adjustable Gas Springs
• Camloc Gas Springs

Guden gas springs have competitive pricing, great quality, are stocked and available for same day shipping.

Benefits of Piano Hinges 

Types of Piano Hinges 

Gas Spring

Gas Springs are found in a variety of applications like office chairs, overhead cabinets, food equipment, manufacturing equipment, agricultural equipment, automotive equipment and more! Gas springs are great for helping control the motion of your lid, door or cover. The gas spring can help keep the lid in the closed position, aid in lifting, and hold the lid in the open position. Gas springs are pressurized with nitrogen gas and contain a small amount of lubricating oil within the cylinder.

Dampers

Dampers are another great way to control the motion of your door, lid or cover. In addition, they're also useful to control the movement of a lever, gear, pedal or linkage mechanism. Each damper is filled with gas and a small amount of lubricating oil. Through a series of chambers and orifices, the movement of gas can slow the motion in the extension or compression of the rod with the tube.

Dampers are available in two basic styles - Compression or Extension. Compression dampers slow the movement of when the damper compresses together. On the other hand, extension dampers slow the motion of a damper when it extends. There is also the option of specialty dampers with dampening in both directions as a custom run.

* Be careful when purchasing struts and shocks because they can be filled with either oil, gas or both*

Strut

A strut is used as one of the components of a vehicles suspension. The suspension is the system of parts that connect the vehicles wheels to the rest of the car. The major functions of a vehicles suspension are to support the vehicle, absorb impact from road irregularities like bumps and potholes and to allow the vehicle to turn the wheels. A strut is involved with helping all these major functions.

A strut is made of two parts, a spring and a shock absorber. The spring is usually a coil spring which is spiral shaped. The spring supports the weight of the vehicle and absorbs the shock of major bumps. The shock absorber also can support the weight of the vehicle but its main function is to dampen the vibrations that occur after major shock. For example, it stops the vehicle from bouncing up and down after a bump.

Shock absorber

Shocks are also used in vehicle suspensions. Although shocks and struts are similar, they are different. Therefore they should not be used interchangeably. Thus, a shock cannot be used to replace a strut and a strut cannot be used to replace a shock. The main difference between the two parts is that a strut is a structural part of a vehicles suspension, where a shock is not. A shock is meant to dampen the vibrations that occur when your vehicle hits major bumps in the road like pot holes.

For example, maybe you need to test operations or conduct maintenance on a mechanical or electrical door. Either way, the flexibility of being able to easily remove a door is a great design feature.
 
Unfortunately separating ordinary hinges can be a problem. Removing ordinary hinges requires detaching the secured pin. Even when the pin is designed to be "loose" as in an ordinary houshold doors, pins can be difficult to remove. 

Luckily there is an easier alternative to the ordinary hinges. Choose from one of our specialty removable hinges. Our lift-off hinges have features built in that enable you to lift off a door without the process of removing a hinge pin. We have a wide variety of lift off hinges including:
