ABSTRACT:
An adjustable backset deadbolt has a casing formed of a sleeve assembly and a rear case. These two elements are independently adjustable to two different backset positions. A deadbolt is movable within the sleeve assembly between extended and retracted positions. There is a swivel rotatably mounted in the rear case and connected by a retractor to a pair of spaced adjustable backset openings in a rearward extension of the deadbolt. Rotation of the swivel provides translational movement of both the retractor and the deadbolt between the extended and retracted positions. The backset adjustment of the deadbolt is brought about by moving the retractor to one of two openings in the deadbolt extension and this adjustment is independent of the adjustment of the backset length of the casing.
