Adams Rite 4900-46-101-628 Deadlatch 1-1/2" Backset, Black

Optimize perimeter control and streamline access with the Adams Rite by ASSA ABLOY 4900 Electrified Deadlatch. Engineered for commercial and institutional doors, this electrified deadlatch delivers reliable security while enabling flexible traffic patterns — a key-controlled bolt holdback permits free entrance or exit-only operation as your schedule requires. The 4900 accepts a standard 1" mortise cylinder and offers a 1-1/2" backset option, fitting narrow stile aluminum doors and retrofitting common preparations without stile modification.

Built for durability, the steel case with corrosion-resistant plating and a solid brass latchbolt withstands heavy use in high-traffic corridors, while reversible handing simplifies installation and reduces maintenance time. For integrated security deployments, the model supports latchbolt monitoring and electrified configurations to tie into access control, alarm monitoring, and surveillance systems. Meets demanding operational needs while reducing downtime and installation cost.
