Springs : Loaded to open
Torsion springs can be added to a hinge to assist in pushing the leaves apart, otherwise known as spring-loading the hinge to open, or "loaded to open."
It is very important to know the direction that the spring legs will push the leaves in relation to how the hinge leaves are mounted. Spring-loaded-to-open hinges are not always used to open a door.
For example, both of these spring hinges are "loaded to open", yet depending on how they are mounted, the hinges can open or close a door.
