Hinge and Pin Anatomy

Hinge Length

Continuous hinges and butt 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. continuous hinges and butt hinges with partial-end knuckles on one leaf may not rotate as freely as full-end knuckles;
