ABSTRACT:
Latch sets must be fitted with a flat face of the latch bolt parallel to a major door face such that the bolt is correctly received in the door frame bolt recess. Latch sets comprise the handles, actuating mechanism, and latch bolt case including the bolt. Here, the latch bolt case is adapted for correct alignment of the latch bolt flat face when the latch bolt case is positioned in a latch bolt case passageway. The latch bolt case is provided with a self-retaining non-cylindrical end portion to avoid the need for recessing the door edge for a latch bolt case plate. Instead, a jig is provided for guiding the case into a retained position within the passageway in which it is a progressive force fit.
