4900 Heavy Duty Deadlatch provides flexible traffic control and easy installation.
Flexibility of traffic control and installation is offered by 4900 Heavy Duty Deadlatches.

Interchangeable, without stile modification, with any MS1850A or MS1850S deadbolt of same backset and faceplate shape. Also retrofits to existing 4500 and 4700 Deadlatch preparations. 1-3/4" minimum door thickness required.
Turn key or operate handle to retract spring-loaded Latchbolt. To hold bolt retracted, push it in and secure by reverse turn of key. Uses any standard 1-5/32" mortise cylinder with MS® dimensioned cam.
