Adams Rite 4911W-36-202-313 Heavy Duty 1-1/8" Deadlatch

Adams Rite 4911W-36-202-313 Heavy Duty Deadlatch is engineered for superior performance and flexibility in traffic control. With a 1-1/8" backset and a durable steel case featuring corrosion-resistant plating, this deadlatch is built to withstand the demands of commercial applications. The radius faceplate comes with weatherstrip, ensuring a secure and snug fit against the door. Designed for both right-hand and left-hand reversible applications, this deadlatch allows for two-way traffic management. A reverse turn of the key while the bolt is held retracted retains the bolt, enabling free entrance at designated times and exit-only at others. It is compatible with the MS1850A and MS1850S deadbolts without requiring stile modifications, and it can retrofit existing 4500/4700 deadlatch preparations. The solid brass latch bolt is easily reversible with just a screwdriver, while the stainless steel auxiliary latch pin enhances security by preventing "loiding" or case-knife entry. Included with the deadlatch are both flat and radius faceplates, and it operates with any standard mortise cylinder using an MS cam. The package includes the necessary machine screws for straightforward installation. Trust the Adams Rite 4911W-36-202-313 for reliable, high-performance door security.
