Product Description
Description: 4900 Heavy Duty Deadlatch provides flexible traffic control and easy installation.
Function: Flexibility of traffic control and installation is offered by 4900 Heavy Duty Deadlatches. A reverse turn of the key while bolt is held retracted retains the bolt, to allow two-way traffic for applications which require free entrance at certain times and exit-only at other times. 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.
Operation: Turn key or operate handle or paddle to retract spring-loaded latch bolt. 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.
Specifications:
Bolt Holdback: While bolt is held fully retracted, a reverse turn of the key retains the bolt, allowing the door to be free swinging.

Case: Measures 7/8” x 5-13/16” x depth. Depth varies by backset (see table on catalog page). Steel with corrosion-resistant plating. Screw-fastened tube spacer brackets allow for cleaner removal when tab mounting.
