ABSTRACT:
A recessed door latch suitable for use in a gymnasium locker door is disclosed which includes a horizontal slide bolt mounted between two deep-drawn nested and flanged dishes which are advantageously fabricated of high-strength thermoplastic such as a polycarbonate. The slide bolt, which also may be fabricated of such plastic, is provided with a groove that mates with a rib projecting from one of the dishes. The deck portion of one of the plastic dishes includes a pair of knock-out plates either of which may be removed to accommodate the articulated handle of the slide bolt.
