| Specifications | 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" [25.4 mm] length, 1-5/32" [29.4 mm] diameter mortise cylinder with MS® cam such as the 4036 Mortise Cylinder or thumbturn such as the 4066Thumbturn, available separately. Lock accepts cylinder from either or both sides. Features: Cylinder Backset: 31/32" [24.6 mm], 1-1/8" [28.6mm], or 1-1/2" 38.1 mm]. Case: Steel with corrosion-resistant plating. Measures 7/8" x 5-13/16" x depth [22.2mm x 147.6 mm 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. Latchbolt: Solid brass. Handing is easily reversible without special tools. Measures 5/8" x 1" x 5/8" [15.9 mm x 25.4 mm x 15.9 mm] throw. Auxiliary Linchpin: Stainless steel. Deadlocks latch bolt to prevent “loiding” or case-knife entry. Faceplate: Measures 1" x 6-7/8" [25.4 mm x 174.6 mm]. Both flat and radius faceplates are supplied. Flat faceplates can also be adjusted in thefield for right or left beveled edge doors. Strike: Standard strike furnished is 4902 for flat jamb where door closes flush or nearly flush.
