Description
The Adams Rite 4920AN is a heavy-duty mortise deadlatch designed for hollow metal or wood doors requiring precise traffic control and security. It features a key-controlled bolt hold-back function that allows doors to free-swing during business hours and exit-only when the bolt latches, solving the challenge of securing entrances while maintaining emergency egress. Ideal for commercial facilities, retail, and institutional buildings.
This lock accepts any standard 1-5/32 inch diameter mortise cylinder with MS cam and is interchangeable with MS1850SN deadlocks of matching faceplate and backset without door modification. The 4506-02 strike is included for ANSI flat-jamb preparation. As an authorized Adams Rite dealer, E.D. Locks offers expert guidance on backset selection, finish options, and installation.
