BUTT HINGE
A hinge made of two matching leaves, one recessed into the shutter panel and the other into the jamb so that they are in contact with the panel.
GAUGE
The thickness of a hinge leaf. LEAF The portion of a hinge extending laterally from the knuckle and which usually revolves around a pin. LEAF WIDTH 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. PIN Rod running the length of the hinge. The pin holds the leaves of the hinge together. LOOSE PIN
Removable hinge pin allowing for separation of hinge leaves. Allows for removal of shutter panel without having to remove hinges.

KNUCKLE LENGTH
The nominal or typical dimension of the knuckle measured parallel to the pin. HINGE LENGTH The length of the leaves measured parallel to the pin. PITCH The dimension from a point on the knuckle to the same point on an adjacent knuckle on the same leaf. PAINT CLEARANCE 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. END PLAY The amount of axial movement between the leaves. KNUCKLE 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. |
PLAIN OR STANDARD ASSEMBLY
This is a surface-type hinge. The leaves lie flat in the same plane when in the open position. Unless otherwise indicated, this type of hinge will be furnished.

SWAGING
The forming of one or both leaves toward or beyond the center of the pin, swaging slightly increases leaf width.
The forming of one or both leaves toward or beyond the center of the pin, swaging slightly increases leaf width.
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 swaged one half the pin diameter.
ONE LEAF FULL-SWAGED
One leaf swaged equal to the pin diameter and both leaves parallel when in a closed position.
One leaf swaged equal to the pin diameter and both leaves parallel when in a closed position.
REVERSE SWAGED
One leaf swaged to simulate reverse assembly. Leaves will not close to a parallel position.
One leaf swaged to simulate reverse assembly. Leaves will not close to a parallel position.
OFFSET
Forming one or both leaves away from the center of the pin. Offsetting slightly decreases leaf width.

STOP HINGE
A hinge manufactured to limit the travel of the leaves to a specified angle.

INSIDE STOP HINGE
Leaves will open from a closed position, leaves parallel to each other, to a stop angle as specified.

OUTSIDE STOP HINGE
Leaves move from an open or flat position and stop at a specified angle.
