Don-jo CW4S Wrap Around Plate Cylindrical Lock

Product Description

The DON-JO CW4S is a classic wrap around plate designed to reinforce and protect door faces around cylindrical locksets. Constructed in a stainless steel finish, this plate fits doors with a 2-3/4 inch backset and a 1-3/4 inch door thickness. It measures 10 inches in length and 4.5 inches in width, providing solid coverage around the lock bore area. Locksmiths, door hardware installers, and finish carpenters install this type of plate during new construction and retrofit applications to strengthen the door face against forced entry and improve the finished appearance of the lockset installation.

The CW4S is suited for residential and light commercial door applications using standard cylindrical locksets. It is a direct surface-mount component applied to the door face, covering the lock prep area. Typical installations include entry doors, office doors, and interior corridor doors where added reinforcement around the cylindrical lock bore is required. The stainless steel finish provides corrosion resistance and coordinates with standard commercial hardware finishes.
