Optimize perimeter security and traffic flow with the Adams Rite by ASSA ABLOY 4900 heavy duty electrified deadlatch. Engineered for storefront and aluminum stile doors, this deadlatch delivers flexible access control—use the key-operated bolt holdback for scheduled free entry or secure exit-only operation when needed. The 4900 accepts standard MS® mortise cylinders, features a narrow 1-1/8" backset, and ships with a flat 4-5/8" mortised faceplate ideal for flush-closing doors. Constructed with a corrosion-resistant steel case, clear anodized finish and solid brass latchbolt, it stands up to high-traffic commercial environments and harsh conditions. Handing is easily reversible in the field without special tools, and the deadlocking latchbolt helps prevent forced entry while providing monitoring options for integration with access control and surveillance systems. Whether you’re specifying electrified deadlatches for schools, retail, or commercial buildings, the Adams Rite 4900 balances durability, retrofit flexibility and secure operation. Specify finish and handing when ordering, or contact us to add the 4900 to your access control and security hardware package.
