Abstract

A first and second spindle housing telescopically receiving an outer and inner spindle, respectively. The outer and inner spindles both have a protruding plate formed on one end for urging a bracket to pull a latch and therefore opening a door. An annular ring rotatably secured on an engaging pin is urgeable by a bar assembly from inside of the door to lock the outer spindle relative to the first spindle housing. An engaging pin, which is rotatable by a key, unlock the blockage between the outer spindle and the first spindle housing. A pair of retention plate assemblies securely retain a lock in a door. The retention plate assembly comprises a retention plate and a pair of bolts.
The retention plate has a pair of tangential tabs, a pair of radial tabs and a pair of threaded through-holes. The pair of bolts each have a threaded end of reduced diameter with respect to the diameter of the bolt. The bolt also has another end manipulatable for releasably engaging its threaded end to the threaded through-hole of the retention plate.
