Don-jo CW3S Classic Wrap Around Cylindrical Lock Plate

Product Description

The DON-JO CW3S is a classic wrap around reinforcement plate designed for cylindrical door locks with a 2-3/4 inch backset on doors measuring 1-3/8 inches thick. This hardware protects the door face around the lockset bore, reinforcing the door against kick-in and forced-entry attempts. Finished in stainless steel, the CW3S suits commercial and residential applications where durability and a clean appearance are both required. Locksmiths, door hardware installers, and general contractors install this type of wrap around during new construction or as a retrofit on existing doors.

The CW3S is suited for interior and exterior doors in light commercial and residential settings where cylindrical locksets are the standard hardware. Its stainless steel finish resists corrosion, making it appropriate for entry doors exposed to moderate environmental conditions. The plate dimensions of 9.7 inches in length and 4.6 inches in width provide solid coverage around the lockset cutout. This product ships as a single unit and is commonly installed alongside cylindrical knob or lever locksets requiring a 2-3/4 inch backset.
