Hinge Offset Measure How To Measure Hinge Distance

Measuring Offsets - The offset of a surfacemount latch is the distance between the surface on which you mount the strike (the jamb) and the surface on which you mount the latch (the door). See Figures 1 and 2.

Straight or Offset Handle - Figure 3 illustrates a straight handle edgemount latch. Figure 4 illustrates an offset handle, which is bent away from the latch body to allow more room for grasping the handle.

Edgemount Latch - Mounts to the edge of the door. Edgemount latches are most commonly found on lightweight reach-in doors, undercounter, and back bar units.

Surfacemount Latch - Mounts on the face of the door. All walk-in doors use surfacemount hardware.

Safety Latch - A walk-in latch that uses a push-rod to prevent accidental entrapment, even if the latch has been locked from the outside. In many states, including California, safety latches are required on all walk-in units.
