Hinge Profiles and Terminology

CLOSED Leaves are parallel, together and at the 0° position.
FLAT Leaves are in line, at the 180° position.
BOTH LEAVES HALF-SWAGED Both leaves are swaged approximately one-half the pin diameter with a minimum clearance between leaves when parallel.
ONE LEAF HALF-SWAGED One leaf swaged one-half the pin diameter.
ONE LEAF FULL-SWAGED One leaf swaged equal to the pin diameter and both leaves parallel when closed.
REVERSE SWAGED One leaf swaged to simulate reverse assembly. Leaves will not close to a parallel position.
REVERSE ASSEMBLY
ONE LEAF FORMED UP 90 DEGREES
ONE LEAF FORMED DOWN 90 DEGREES
MULTIPLE PIN HINGES Multiple pin hinges for double action. Available in Reverse Assembly, Swaged and formed configuations.

LENGTH The length of the leaves measured lenthwise to the pin. OPEN WIDTH The overall dimension of the leaves measured across the pin. LEAF That portion of a hinge extending away from the knuckle at 90° to the pin. LEAF WIDTH The dimension from the center of the pin to the outer edge of the leaf.
KNUCKLE The hollow circular part through wihch a pin is passed. (Also called curl.) KNUCKLE LENGTH The dimension of the knuckle measured parallel to the pin. PIN The rod running through the center of the knuckles.
