LENGTH
Continuous hinges can be cut to exact length as required. Hinges should, however, be designed to a length that is a multiple of the knuckle length to eliminate partial knuckles. If a partial knuckle length cannot be avoided, please keep the following points in mind: 1) partial knuckle lengths should be the same as or larger than the knuckle diameter; 2) when partial knuckles are required on both ends, they should be on the same leaf; 3) please be advised that continuous hinges with partial-end knuckles on one leaf may not rotate as freely as full-end knuckles.






Industrial HingesPIN RETENTION
All standard continuous hinges are stocked with loose pins and flush cut ends, with the exception of steel and stainless steel hinges in thicknesses of .025 and .035" which will be staked to retain the pin. The following are among the methods used to retain the pins.

Flush pin staked
The most economical way to retain a pin is by staking it on the topside or backside of the knuckle.

Pin spun both ends
This method is normally used only for tamper-proofing or for applications with severe vibrations.




PIN MATERIAL
All standard hinges are supplied with like pin and leaf materials. However, any hinge can be ordered with a pin material different from its leaf material. For example, you may request steel hinges with brass pins.


PIERCING
Many designs for piercing are available. When ordering or requesting a special hinge quotation, include: hinge dimensions, hole diameter and type, hole centers, edge dimensions and end dimensions. Ask about our standard hole patterns. Following are several common piercing designs:

Special Hinges

Note: Countersinking is the removal of metal, whereas coining is the displacement of metal, and in some cases will leave a slight bulge on the leaf edge.

FORMED LEAVES
Formed special hinge leaves can be supplied in a variety of configurations (including those illustrated below). Dimensions should be taken from the pin center line and inside of forms. Unless otherwise indicated, the inside radius of a form is the same as the material thickness.

Custom HingesUNEQUAL LEAVES
Unequal leaves are available on all hinges. Widths are measured from the pin center line to the leaf's outer edge. For the most economy, unequal open width should be a product of a standard hinge width; however, unequal leaves with nonstandard widths are also available.



Notched Leaves

Some of the more commonly used designs:





FASTENERS
Hinges can be pierced and installed with self-clinching fasteners per customer specifications.


SPRING-LOADED HINGES
Any of our standard continuous hinges can be spring loaded. This type of hinge is produced using torsion springs, complying with your specifications. When ordering, include a sketch that indicates spring action (open or closed), locations, force, material and all other pertinent information.


Custom Slip Joint Hnges
SLIP-JOINT HINGES
Slip joint hinges or "take-apart" hinges are normally used when requirements call for doors to be removed. Indicate right- or left-handed when ordering.





BUTT HINGES

Note: Hinges will be plated assembled. Only hinges shipped to customers unassembled will be plated unassembled. Aluminum hinges cannot be anodized with brass or stainless steel pins.
