This standard-duty deadlatch features a radius faceplate and a 1-1/8 inch backset, making it a versatile choice for retrofitting older MS1850 Deadlocks and discontinued 4250 Deadlatches without the need for modifications. Designed for establishments such as hospitals, banks, and retail stores, this deadlatch supports two-way traffic by allowing free entrance at specified times while providing exit-only access during others. The 4531-35-201-628 includes a spring-loaded latchbolt that can be easily retracted using a standard mortise cylinder with an MS cam. Once the bolt is held retracted, a simple reverse turn of the key retains the bolt, enabling seamless door operations. Crafted from durable steel with a corrosion-resistant finish, this deadlatch boasts a 1/2 inch throw latchbolt and an auxiliary bolt to prevent unauthorized entry. Each unit comes individually boxed with a flat mortised strike and machine screws for straightforward installation. Measuring 1-1/4 inches by 7-13/32 inches, the faceplate is designed to fit standard mortise applications, ensuring compatibility and ease of use. With a five-year limited warranty, the Adams Rite Retrofit DeadLatch is a smart investment for enhancing security and functionality.
