Prime-line E 2164 Mortise Lock, Steel, 45 Degree Keyway, 4-5/8 In.

This mortise lock is designed to replace old or broken locks on sliding patio doors without requiring full door replacement. Constructed of steel components with a round faceplate and an adjustable, spring-loaded hook latch projection, it provides a reliable locking solution for wood and vinyl patio doors. The lock features a 45-degree angled keyway position when locked, and includes an adaptor faceplate that accommodates various mounting requirements on mortise-style, surface-mounted patio door handle sets.

Before purchasing, verify that this lock matches your existing setup by checking the mounting hole spacing (3-11/16 in. and 4-5/8 in. on center), faceplate style (rounded ends), keyway angle (45 degrees), and rear housing corners (square). This mortise lock is widely used by patio door manufacturers and is not a universal fit, so proper comparison ensures compatibility with your specific door hardware.
