ABSTRACT:
An integrated mortise lock trim mechanism is provided for mounting on the surface of a door and has a handle turning a spindle that extends into the door to operate a lock mechanism mounted therein. The trim assembly is pre-assembled and has a retracting spindle that extends between the trim mechanism and the lock mechanism to accommodate varying door thicknesses. The preferred assembly utilizes a cover plate, spring and mounting plate assembly holding a pair of alignment through bolts. This assembly is fit onto a door handle and secured to the door handle by a cap nut. An elongated spring is disposed in the handle and is secured to a spindle which axially extends from the handle. The spindle is automatically retracted or extended to optimally fit into the hub of a mortise lock.
