ABSTRACT:
An improved and simplified lock housing assembly for positioning and retaining lock or latch assemblies in cutouts in glass doors provided for that purpose which, outside of standard components such as screws, uses extrusion produced components so that the requirement for heavy machining and complex manual assembly is eliminated. The assembly includes a pair of spacers cut from the same extrusion which nest against an extruded elastomeric, channel shaped grommet about the cutout and position the lock assembly. The spacers are retained in the plane of the door by lengths of extruded plate which are fastened by screws to the opposite sides of the spacers and extend over upper and lower portions of the grommet. The screws and the grommet portion still exposed are in turn covered by extruded cover plates which include channels which slide over and dovetail with chamfered edges of the screw plates. The cover plates are, in turn, retained by the lock cylinder of the lock assembly or portions such as the handle and latch plate of the latch assembly.
