ABSTRACT:
An improved deadbolt lockset is provided in which one of two different backset distances is facilitated in a single latch assembly. At least one planar side plate coupled to a deadbolt extension is provided and is slidably contained within a hollow latch case. Movement of the side plate determines the distance from the face plate of the assembly to the axis of an actuating assembly. The latch case includes slots formed therein for positioning the actuating assembly and to allow movement of the side plates.
