Abstract: An adjustable backset deadbolt assembly providing operational and structural improvements. The deadbolt assembly can provide adjustability between a first backset dimension and a second backset dimension for allowing installation in doors conforming to various industry standards. The deadbolt assembly can provide adjustability between backset dimensions by relative rotation between the inner bolt housing and the outer housing. The inner bolt housing may be provided with a depressible snap finger to allow insertion of a protrusion thereon into a slot in the outer housing. In some embodiments, the slot is provided substantially helically through an angle of 360 degrees to provide common orientation of parts in each backset dimension. The outer housing may be provided to integrally form a cam housing and a bolt housing.

Abstract: A retainer clip is used for retaining a lock plug within a bore of a lock housing. The retainer clip includes a generally arcuate body disposeable about the plug outer surface and having a radial retention surface positionable generally against a housing end surface so as to prevent axial displacement of the plug along the bore. Two projections are each disposed proximal to a separate end of the body, each projection being disposeable within a separate plug opening when the body is disposed on the plug to retain the clip engaged therewith. The clip body has a hinge, a first arm portion extending between the hinge and one free end and a second arm portion extending between the hinge and the other end. The hinge is configured so that the two arm portions are deflectable generally about the hinge to move with respect to each other during installation and removal.
