Adams Rite 4531-35-101-335 Retrofit DeadLatch 1-1/8 Backs is a standard duty solution designed for effective traffic control in commercial settings. With a radius faceplate and a backset of 1-1/8 inches, this deadlatch provides flexibility for buildings such as hospitals, banks, and retail stores, facilitating two-way traffic management during specified hours. The 4530 series deadlatch features a robust construction with a steel case and corrosion-resistant plating, ensuring durability over time. The latchbolt is spring-loaded, with a 1/2-inch throw, and includes hardened steel internal pins for enhanced security. A unique feature is the bolt holdback mechanism, which allows the bolt to be retained in a retracted position through a reverse turn of the key, enabling free swinging of the door when needed. Designed to retrofit seamlessly into existing preparations for older MS1850 Deadlocks and discontinued 4250 Deadlatches, installation is straightforward and efficient. This model is compatible with any standard mortise cylinder featuring an MS cam, and it comes individually boxed with a flat mortised strike and machine screws for easy mounting. With a focus on reliability and user convenience, the Adams Rite 4531-35-101-335 Retrofit DeadLatch is an ideal choice for those seeking a dependable locking solution.
