Don-jo CW81PB Wrap Around Plate Polished Brass Cylindrical Lock

Product Description

The DON-JO CW81PB is a classic wrap around reinforcement plate designed for cylindrical door locks. It fits doors with a 2-1/8 inch bore hole, a 2-3/4 inch backset, and a door thickness of 1-3/4 inches. The plate is finished in polished brass, making it suitable for installations where appearance and durability both matter. This hardware is installed by locksmiths, door hardware specialists, and general contractors during new construction or lock replacement work. It reinforces the door face around the lockset, reducing vulnerability at the bore site and improving overall door security.

The CW81PB is used in residential and light commercial door applications where a cylindrical lockset is being installed or replaced. It is appropriate for single-bore door prep with a 2-3/4 inch backset, which is the standard backset for most residential cylindrical knob and lever locksets. The polished brass finish suits interior and entry doors in settings that call for traditional or classic hardware aesthetics. Installation is straightforward on 1-3/4 inch thick doors, the most common thickness for residential entry and interior doors.
