Adams Rite 4900 Heavy Duty Deadlatch, Flat Faceplate, Guarded Latch, Flat/Standard Jamb Strike

4900 Heavy Duty Deadlatch provides flexible traffic control and easy installation

Function:

Flexibility of traffic control and easy installation is offered by 4900 Series Heavy Duty Deadlatches. 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. This allows a “locked” entrance to be used as an exit by visitors already in the building. 1-3/4″ [44.5 mm] minimum door thickness required. Interchangeable, without stile modification, with any MS1850S deadbolt of same backset and faceplate shape. Also retrofits to existing 4510 and discontinued 4700 Deadlatch preparations.

Operation:

Turn key or operate handle or paddle to retract spring-loaded latchbolt. To hold bolt retracted, push it in and secure by reverse turn of key. Lock accepts any standard 1″ length, 1-5/32″ diameter mortise cylinder with MS® cam such as the 4036 Mortise Cylinder or thumbturn such as the 4066 Thumbturn, available separately. Lock accepts cylinder from either or both sides.

• Case: Steel with corrosion-resistant plating. Measures 7/8″ x 5-13/16″ x depth. Depth varies by backset. Screw-fastened tube spacer brackets allow for cleaner removal when tab mounting.
• Bolt Holdback: While bolt is held fully retracted, a reverse turn of the key retains the bolt, allowing the door to be free swinging
