Hinges and Hardware 101 - Bending Hinge Leaves

Guden bent hinge leaf

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.

Hinges and Hardware 101 - How to Compress a Gas Spring

Guden gas springs

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

Hardware Around Town - Guden Catch and Strike Sets

Guden Draw Pull Catch and Strike Sets

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.

Which Style Of Spring-Loaded Hinge Is Best For My Application?

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.

Hinges and Hardware 101 - Dimensioning a slotted hole

Guden slot dimensions

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.

Hinges Around Town - Guden Hinge Paint Clearance

Guden hinge paint clearance

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.

Hinges and Hardware 101 - Staked Pins

Guden hinge staked pin

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.

Hinges Around Town - Guden 3 Leaf Hinges

Guden 3 leaf hinges

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.

What are the 3 most popular ways to mount a hinge?

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:


— 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

Fastened Hinge — 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

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.

Hinges and Hardware 101- Guden Heavy Duty Hinges

Guden heavy duty hinges

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.

Hardware Around Town - Guden Strap and T Hinges

Guden strap and t hinges

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.

Hinges and Hardware 101 - Unequal Leaf Hinges

Guden unequal leaf hinges

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.

Hinges and Hardware 101 - Springing Into Action - Guden

Guden spring latch hinges

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.

Hardware Around Town-Choosing the Best Handle or Pull-Guden

Guden handles and pulls

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.

Hinges and Hardware 101 - Full Knuckles VS. Partial Knuckles

Guden continuous hinges

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. 

We always recommend that the cutting be done in a size that is equally divisible by the knuckle length because it makes for a nicer neater cut, and is usually more aesthetically pleasing to look at. 
Take this hinge shown here which has one partial knuckle on one end.  I can see it's slightly deformed from cutting through the knuckle, and it draws the eyes of most hinge enthusiasts because it's not uniform in size with the rest of the knuckles. And who would want to draw unwanted attention to their hinges?

HSI: Case of the Not so Invisible Gas Spring - Guden

Guden black nitride gas springs

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.

Hardware Around Town - Guden Rod Pulls

Guden Rod Pulls

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:

Gas Spring vs. Spring Hinge - Guden

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.
Guden Gas Springs Gas Springs are a piston and rod assembly that is filled with pressurized gas and a small amount of lubrication and damping oil.
  • A one piece unit requiring ball studs or brackets for mounting
  • Painted steel or stainless steel construction
  • Application typically also requires a hinge on the door
  • Mounting can be designed to hold door in open and/or closed position so no additional catches or supports are needed
  • Often requires operator to assist the lid opening until gas spring takes over
  • Additional styles available: Locking gas springs, Friction stop gas springs, Miniature gas springs
  • Wide range or gas spring pressures allow for use on very light to very heavy doors
  • Also known as Gas Struts, Gas Pistons, Gas Shocks
  • How to mount a gas spring
Guden Spring Hinges Spring Hinges are a standard hinge with one or more knuckles removed and replaced with a torsion spring.
  • A one piece unit: with holes requires screws for mounting, or blank for welding
  • Spring-loaded-to-open or spring-loaded-to-close versions
  • Depending on how they are mounted, can be used to open or close a door
  • Typically used on vertical doors, but can be used on horizontal lids or covers too
  • Work best on light to medium light weight doors
  • Will push hinge leaf without requiring an outside force so may require a catch or latch to keep in desired position
  • Steel, plated steel, stainless steel or aluminum construction
  • Torsion spring strength can be adjusted by adding more springs or increasing strength of each spring
  • Doesn't require additional space inside cabinet for mounting
  • Provides immediate motion to the door upon release

Hinges and Hardware 101 - Corrosion resistance - Guden

Guden plastic hinges

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

Case of the Reversed Hinge Leaves - Guden

Reverse assembly Guden hinge

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.

Hinges Around Town - Strange Slip - Guden

Guden custom slip joint hinge

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

Hinges and Hardware 101 - corners - Guden

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.

HSI: Hardware Scene Investigation- Case of the Missing Pin

Guden pin retention

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. 

Why is paint clearance important? - Guden

Guden Hinges and Hardware

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 (

What is a Gas Spring - Guden

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.

What is a Gas Strut - Guden

Gas Strut

Many people tend to be confused about the differences between gas struts, dampers, gas springs, gas shocks and other words used to describe similar products. Sometimes these terms are even used interchangeably. In order to make sure that you are purchasing the right product, carefully examine the different functions of products that people sometimes call "gas struts."

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 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*


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.

What is a Butt Hinge - The "Classic" Door Hinges - Guden

Butt Hinges

  • a type of hinge that is attached to the abutting surface of a door or lid.
 Butt hinges are one of the most popular hinges used today. When you look at most commercial doors, you will probably see a butt hinge supporting the door. These hinges are usually about 6 inches in length or shorter. They are installed for a variety of different applications and have many uses. 

A butt hinge is composed of two hinge leaves. One is usually attached to a fixed component such as a wall or door jamb and the other is attached to a moving component such as a door. These hinges are usually mortised or recessed into both surfaces.  The pin secures the leaves together and allows for movement. 

Most butt hinge pins are removable to allow for door removal, but some are non removable for security purposes. Check out our selection of removable pin butt hinges.

A more secure solution than the removable butt hinges are butt hinges with staked pins. Staked pins hold tight, but with some effort the pin can be driven out and removed. We have a huge selection of butt hinges with staked pins.

A great solution for secure hinges is choosing a butt hinge with pins spun on both ends. This pin will not go anywhere unless you grind off one of the spun ends. Browse our selection of nonremovable butt hinges.

Some butt hinges can even contain springs to allow for a supported opening or closure. Review our selection of spring butt hinges

Butt hinges can be drilled and supplied with whatever hole pattern you choose. For more information regarding custom butt hinges, visit our customization page.

A couple of common misconceptions about gas springs:

  • A 10 lb door requires a 10 lb force spring ➔ rarely true! The force required is usually several times higher than the weight of the door.
  • You only need one spring ➔ Yes, but your door is likely to twist with one spring.  Using two gas springs delivers better performance, reliability and safety.
