ABSTRACT:
An elongated bolt extension member is coupled to the bolt head of a door latch, and a pivotally mounted latch cam engages the elongated bolt extension member to slide the latch into and out of its retracted position. The elongated bolt extension member has a top surface with two spaced openings corresponding to two different backset distances. The latch cam extends into one or the other of the openings to adjust the backset distance.
