Description
The Adams Rite 4511 Series mortise deadlatch provides flexible traffic control for hospitals, banks, and commercial buildings. A reverse key turn holds the bolt retracted, enabling two-way traffic during business hours and exit-only control afterward. The steel case with corrosion-resistant plating and hardened steel pins deliver durable, reliable performance for high-traffic entrances.
This lock is interchangeable with MS1850A or MS1850S deadbolts of matching backset and faceplate without stile modification. Available in four cylinder backsets (7/8 In., 31/32 In., 1-1/8 In., or 1-1/2 In.), with reversible handing requiring no special tools. Contact our authorized dealer experts at sales@edlocks.com or 1-877-207-6067 for backset selection, strike options, and cylinder compatibility guidance.
