ABSTRACT:
A method is provided for attaching separable mounting tabs to a mortise lock housing, including the steps of providing a hollow mortise lock housing in the form of a rectangular parallelepiped with a first side adapted to lie in a door edge and to provide at least one opening for a bolt, providing one slot at each of top and bottom edges, as installed, of the first side of the lock housing, the slots providing narrow openings for capturing mounting tabs at top and bottom corners of the lock housing, providing two mounting tabs, each having a first end portion for mounting an end of the faceplate and a second end for capturable insertion in the slots in the lock housing, the tabs further having a substantially right angle bend between the first end and the second end, orienting the mounting tabs such that the first ends are substantially parallel to the first side of the lock housing and project above and below the top and bottom corners of the first side of the lock housing, respectively, and the second ends are substantially parallel to top and bottom sides of the lock housing, the right angle bends being aligned with the slots, inserting the mounting tabs into the slots to place the second ends thereof in contact with top and bottom sides of the lock housing and to engage means for preventing tipping of the tabs with the first side of the lock housing, and attaching the coverplate to the lock housing.
