ABSTRACT:
A lock assembly is described for a door, the assembly including a gib having at least one flange. A locking unit has a first wall including an edge portion on the wall for sliding into the gib and for engaging the flange on the gib such that the locking unit is retained by the gib. A locking latch is movable between an unlocked position in the locking unit and a locked position such that the locking latch engages a wall in a frame when in the locked position. A second wall extends from the first wall of the locking unit in a direction substantially non-parallel to the first wall of the locking unit to keep the door closed when the locking latch is in the locked position.
