Overview
Optimize perimeter security and occupant flow with the Adams Rite by ASSA ABLOY 4920AN Series heavy-duty deadlatch. Designed for commercial entrances and access control systems, this deadlatch combines durable construction with adaptable traffic management: a key-controlled bolt holdback enables two-way traffic when needed and exit-only operation at other times—useful for lobbies, corridors, and secure facilities. Built for installers, the 4920AN accepts a 2-3/4" backset, fits a minimum 1-3/4" door thickness, and is reversible for left-hand or right-hand (LH or RHR) applications, cutting retrofit time and labor. Constructed with a corrosion-resistant steel case and solid brass latchbolt in a clear anodized finish, it stands up to heavy use while integrating smoothly with electrified deadlatches, access control, surveillance, and monitoring systems. Interchangeable with MS1850SN preparations and ANSI-sized for easy replacement of older models, the 4920AN delivers reliable security performance where it matters. Specify the Adams Rite 4920AN for commercial, healthcare, education, or government projects—contact us to order or confirm compatibility with your access control setup.
