The DON-JO CW1210B is a classic wrap around reinforcement plate designed to protect door surfaces around cylindrical locksets. It features a 2-1/8 inch hole to accommodate standard cylindrical lock cylinders and is sized for a 2-3/4 inch backset on 1-3/4 inch thick doors. At 12 inches in length, it provides solid coverage across the door face and edge, reducing vulnerability to forced entry at the lock location. This plate ships in an oil rubbed bronze finish and is installed by door hardware technicians, locksmiths, and general contractors during new construction or hardware upgrade projects.
The CW1210B is suited for commercial and residential door applications where cylindrical locksets require added reinforcement. It is a direct-fit solution for standard door preparations using a 2-3/4 inch backset on 1-3/4 inch doors, making it appropriate for most hollow metal and wood door assemblies in retrofit or replacement scenarios where the existing door face shows wear or damage around the lock bore.
Designed as an OEM-style reinforcement plate for cylindrical lockset installations on standard 1-3/4 inch doors with a 2-3/4 inch backset and a 2-1/8 inch bore hole.
Installation is typically performed by a locksmith or door hardware technician. Ensure the door is secured and the existing lockset is removed before fitting the wrap around plate. Verify door thickness and backset measurement match the plate specifications before installation. Follow applicable building code requirements for door hardware reinforcement in your jurisdiction.
