Description
The Adams Rite 4920AN is a heavy-duty mortise deadlatch engineered for hollow metal and wood doors requiring precise traffic control and security. Its key-controlled bolt hold-back feature allows doors to free-swing during business hours while enabling secure locking when needed, making it ideal for commercial entrances, offices, and facilities managing access throughout the day.
The 4920AN fits standard ANSI preparations and works with any mortise cylinder featuring an MS cam (order separately). Installation is straightforward on both flat and beveled-edge doors. As an authorized Adams Rite dealer, E.D. Locks provides expert specification guidance and fast shipping.
