Description
The Adams Rite 4920AN is a heavy-duty mortise deadlatch designed for hollow metal and wood doors requiring precise traffic control. 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 that must function as both controlled entry and emergency exit points.
This mortise lock fits doors prepared to ANSI specifications and is interchangeable with MS1850SN deadlocks without modification. The steel case features corrosion-resistant plating, solid brass latch bolt, and stainless steel auxiliary latchpin to prevent forced entry. As an authorized Adams Rite dealer, E.D. Locks provides expert guidance on backset selection, finish options, and cylinder pairing.
