发明名称 Latch assembly having selectable backset distance
摘要 A latch mechanism is provided in which one of two different backset distances is facilitated in a single latch assembly. A latch slide which is used to retract the latch bolt of the assembly is provided with a removable latch slide extension which determines the distance from the face plate of the assembly to the center of the actuating assembly. The latch slide and bolt are carried within a latch case or housing which includes slots formed therein. The actuating assembly includes jaws which fit into the slots in order to fix the position of the latch assembly with respect to the actuating assembly upon final installation of the mechanism into the door.
