The thickness of a hinge leaf.
The portion of a hinge extending laterally from the knuckle and which usually revolves around a pin.
The dimension from the center of the pin to the outer edge of the leaf.
HINGE WIDTH (same as open width)
The overall dimension of the leaves measured perpendicular to, or across, the pin.
Rod running the length of the hinge. The pin holds the leaves of the hinge together.
Removable hinge pin allowing for separation of
hinge leaves. Allows for removal of shutter panel without having to remove hinges.
The nominal or typical dimension of the knuckle measured parallel to the pin.
The length of the leaves measured parallel to the pin.
The dimension from a point on the knuckle to the same point on an adjacent knuckle on the same leaf.
The minimum dimension between the outer face of the knuckle and the opposing edge of the cutout over the hinge's entire range of pivotal movement.
The amount of axial movement between the leaves.
The hollow circular part at the joint of a hinge through which a pin is passed. The knuckle is often called a loop, joint, node or curl.
