ABSTRACT:
A cylindrical lock assembly (20) includes an inside subassembly (22) and an outside subassembly (24) which are assembled with a door (326). Each subassembly (22,24) includes a rose liner (26,38), a return spring cassette (28,40), a rose (30,42), a lever (32,46) and a lever insert (34,48). The inside subassembly (22) also includes a turn button (36) and the outside subassembly (24) includes a cylinder lock (44).
A pair of mounting blocks (258,260) are contained within the chassis (50) to facilitate threaded connection of the chassis to the rose liners (26,38) which are assembled on respective sides of the door (326) and thereby provide an anti-rotation mounting for the chassis.
