Adams Rite 4512-15-121-628 DeadLatch 7/8" Backset

Adams Rite 4512-15-121-628 DeadLatch 7/8 Backset offers reliable security and flexible access control, making it an ideal choice for commercial applications. This standard duty deadlatch features a flat faceplate and a guarded latch, ensuring robust performance with a 7/8" backset. Designed for ease of use, the lock allows for two-way traffic; a reverse turn of the key while holding the bolt retracted retains the bolt, facilitating free entry during business hours and exit-only during restricted times. Constructed from durable steel with corrosion-resistant plating, this deadlatch is designed for long-lasting service. The all-metal latch bolt, featuring hardened steel internal pins, enhances security by preventing "loiding" or case-knife entry. The lock is reversible for left-handed or right-handed installations without the need for special tools. Included in the package is a standard 4902-01 strike plate, compatible with flat jambs. Optional strikes are available for various door configurations. The Adams Rite 4512 is suitable for doors measuring 1-3/4" to 2" thick and operates with any standard mortise cylinder with an MS cam. Individually boxed, it comes complete with mounting screws, ensuring a straightforward installation process.
