Adams Rite 4920AN-55-602-313 ANSI DeadLatch 2-3/4 is a heavy-duty solution designed for both hollow metal and wood doors, adhering to the American National Standards Institute (ANSI) specifications. This deadlatch features a robust flat faceplate with a 2-3/4 inch backset and is equipped with a 4-7/8 inch flat mortised strike, available in a dark bronze anodized finish. Engineered for precise traffic control, the 4920AN incorporates a key-controlled bolt hold-back feature that allows the door to swing freely during specified hours and remain exit-only when latched. Its steel case is coated with corrosion-resistant plating, ensuring durability, while the solid brass latch bolt provides a reliable locking mechanism. The easily reversible handing can be adjusted with just a screwdriver, making installation straightforward for both commercial and residential applications. The stainless steel auxiliary latchpin enhances security by preventing "loiding" or case-knife entry.
