Adams Rite 4530-25-201-628 Retrofit DeadLatch is a versatile solution for managing door traffic in commercial settings. This standard-duty deadlatch features a flat faceplate and a 31/32-inch backset, making it an ideal replacement for older MS1850 Deadlocks and discontinued 4250 Deadlatches, requiring no alterations for installation. The 4530 model allows for flexible access control; a reverse turn of the key while the bolt is held retracted enables two-way traffic, perfect for environments like hospitals, banks, and retail stores where entrance and exit needs vary throughout the day. Constructed from durable steel with corrosion-resistant plating, the deadlatch includes a 2-5/8-inch flat mortised strike, and a reversible handing feature for easy adaptation to various door orientations. The spring-loaded latchbolt measures 1/2-inch by 1-inch, ensuring reliable engagement and security. Additionally, it incorporates an auxiliary bolt to prevent unauthorized entry methods. The deadlatch is individually boxed with mounting screws and includes compatibility for any standard mortise cylinder with MS cam. With options available for backsets, faceplate shape, strike type, and finish, the Adams Rite 4530-25-201-628 Retrofit DeadLatch is a robust choice for enhancing security and functionality in commercial door applications.
