Don-Jo 3-CW Stainless Steel Wrap-Around Plate | 1-3/8" Door Reinforcer (2-3/4" Backset)

The Don-Jo 3-CW Stainless Steel Wrap-Around Plate is a high-performance security and restoration solution designed specifically for thinner 1-3/8" thick doors that require a commercial-standard 2-3/4" backset. Measuring 4-1/4" wide x 9" high, this heavy-duty door reinforcer provides 360-degree structural integrity by "sandwiching" the lock area in industrial-grade steel. It is the premier solution for door surface repair, designed to conceal "ghosting," splintering, or unsightly mounting marks left behind by previous hardware transitions.

Precision-manufactured with a 2-1/8" hole prep, the 3-CW allows for the installation of standard cylindrical locks on doors where the lock hole is set further from the edge. By reinforcing the most vulnerable point of the door leaf, it serves as a critical solution for door security, preventing the door from splitting during forced entry or high-frequency use.
