Adams Rite 4900-35-202-628 4900 Heavy Duty Deadlatch, Standard Faceplate, 1-1/8" Backset, LH or RHR Handling for Radius 2-5/8" Mortised Strike, Clear Anodized

Optimize perimeter security and traffic flow with the Adams Rite by ASSA ABLOY 4900 electrified deadlatch — designed for commercial entrances where controlled access, reliable egress, and integration with monitoring systems matter. This heavy-duty electrified deadlatch delivers the flexibility of key-controlled bolt hold-back, allowing doors to be free-swinging at select times while remaining secure when locked. Built for installers, the 4900 retrofits common MS1850S preparations and older 4510/4700 cuts, and offers reversible LH or RHR handing without special tools. Key specifications include a 1-1/8 inch backset option, acceptance of standard 1" mortise cylinders, and compatibility with a radius 2-5/8 inch mortised strike. The steel case with corrosion-resistant plating and clear anodized finish stands up to high-traffic environments, while the solid brass latchbolt and latchbolt monitor support integration with access control, alarm, and surveillance systems. Ideal for education, healthcare, retail, and commercial facilities that require trusted security hardware and seamless monitoring, the 4900 provides a practical balance of durability and control. Specify handing and finish, then add compatible cylinders or paddles as needed—order now to upgrade your access control and door security.
