Description
The Adams Rite 4900 Series Mortise Deadlatch provides flexible traffic control for commercial doors, allowing two-way passage during open hours and exit-only restriction when needed. A reverse key turn securely holds the bolt retracted. This steel mortise lock with corrosion-resistant plating solves access management challenges in offices, hospitals, schools and multi-tenant buildings.
Compatible with MS1850A and MS1850S deadbolts of the same backset and faceplate, and retrofits existing 4500/4700 preparations without stile modification. Includes flat and radius faceplates, strike, and mounting screws. For expert guidance on backset selection (31/32 in., 1-1/8 in. or 1-1/2 in.), cylinder compatibility, or retrofit applications, contact our authorized dealer specialists at sales@edlocks.com or 1-877-207-6067.
