Abstract: A lock assembly for use with a bolt movable from a retracted position to an extended position. The lock assembly includes an exterior assembly and an interior assembly having an interior actuator manually operable to move the bolt between the retracted position and the extended position. The exterior assembly includes an exterior actuator manually operable to cause the bolt to move from the retracted position to the extended position and inoperable to move the bolt from the extended position to the retracted position.

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.
