The Problem

Broken mortise latch on a boat lock assembly. To investigate the problem with broken latches, the client dismantled them and and uncovered some broken plastic (injection molded) parts inside.

The mortise latch makes use of a small rocker/lever arm, which transmits the rotation of the handle to the tongue, which retracts, unlatching the door. The tongue, the rocker, or both were broken on each of the three latches. This particular brand of mortise latch sells for roughly $350 with no option for replacement parts.

The Solution

Replik8 Studios 3D model and printed a new rocker arm and to match the old ones perfectly.
