Adams Rite 4900-35-201-628 4900 Heavy Duty Deadlatch, Standard Faceplate, 1-1/8" Backset, LH or RHR Handling for Flat 2-5/8" Mortised Strike, Clear Anodized

Deliver professional-grade access control with the Adams Rite by ASSA ABLOY 4900 heavy-duty electrified deadlatch, engineered for secure entrances, retail storefronts and institutional doors. This electrified deadlatch provides flexible traffic control with a key-operated bolt hold-back so the door can be two-way at scheduled times and exit-only when needed—ideal for busy facilities, security-sensitive sites and monitored entryways. The 4900 accepts standard MS mortise cylinders and thumbturns, fits a 1-1/8" backset (also available in narrow options) and installs with the supplied flat faceplate and 2-5/8" mortised strike for a precise, low-profile fit. Constructed with a steel case, solid brass latchbolt and corrosion-resistant clear anodized finish, it resists wear in high-traffic environments and integrates smoothly with access control systems, surveillance monitoring and alarm wiring. Handing is easily reversible with no special tools, and it retrofits common deadlatch preparations for fast upgrades. Specify finish, backset and strike when ordering. Upgrade your security hardware with the Adams Rite 4900 for reliable, serviceable door control—add to your access control solution today.
