Adams Rite 4512-45-628 Mortise Lock Satin Aluminum Clear Anodized

4510 Standard Duty Deadlatches offer versatile traffic management during and post business hours. This series features a reverse key turn while the bolt is held back, retaining the bolt to facilitate two-way traffic in hospitals, banks, stores, and other buildings needing free entrance at specific times and exit-only at others. They're interchangeable with any MS1850A or MS1850S Deadlock of the same backset and faceplate shape, though they don't match the MS Deadbolt's maximum security. The lock case is steel with corrosion-resistant plating, available in four cylinder backsets: 7/8 In., 31/32 In., 1-1/8 In., or 1-1/2 In. The all-metal latch bolt has hardened steel internal pins, with reversible handing. An auxiliary bolt deadlock prevents 'loiding' or case-knife entry. The standard strike is 4902-01 for flat jambs where doors close flush or nearly flush. Other strikes are available. Turn the key or operate the handle to retract the spring-loaded latch bolt. To hold the bolt retracted, push it in and secure with a reverse key turn. It uses any standard mortise cylinder with an MS cam. It's individually boxed with a strike and machine screws for mounting, with cylinders, paddles, or handles available at extra cost.
