Adams Rite 4900-45-201-335 4900 Heavy Duty Deadlatch, Standard Faceplate, 1-1/2" Backset, LH or RHR Handling for Flat 2-5/8" Mortised Strike, Black Anodized

For commercial entrances that require both robust security and flexible traffic control, the Adams Rite by ASSA ABLOY 4900 electrified deadlatch delivers reliable performance and simple integration. This heavy-duty deadlatch combines a key-controlled bolt hold-back — enabling two-way traffic or exit-only operation — with reversible LH/RHR handing that can be changed in the field with just a screwdriver. The 4900 series accepts standard mortise cylinders and is offered in a durable black anodized finish; the 1-1/2" backset and solid brass latchbolt ensure consistent operation on narrow-profile aluminum and hollow metal doors. Built with a corrosion-resistant steel case and auxiliary linchpin deadlocking, the lock resists tampering and “case-knife” attacks while supporting latchbolt monitoring for access control and security system integration. Ideal for retail storefronts, secured offices, and monitored egress points where surveillance and access control matter, the 4900 simplifies installation and retrofits into common deadlatch preparations.
