4920AN Heavy Duty Deadlatch provides flexible traffic control and easy installation for wood or hollow metal doors.

Function

Flexibility of traffic control and installation is offered by 4920AN Heavy Duty Deadlatch. A key-controlled bolt hold-back feature allows for two-way traffic for applications which require free entrance at certain times and exit-only at other times.

Interchangeable, without stile modification, with any MS1850SN Deadlock of same backset and faceplate shape. Replaces 4520 and discontinued 4720 ANSI Deadlatches. For hollow metal or wood doors prepared for hardware according to the specifications of the American National Standards Institute (ANSI).

Operation

Turn key or operate handle or paddle to retract spring-loaded latchbolt of the 4920AN Heavy Duty Deadlatch. To hold bolt retracted, push it in and secure by reverse turn of key.
