Manufactured from zinc die-cast, this lock offers solid construction suited for residential window hardware replacement and repair. It measures 2-7/16 inches x 1-11/16 inches with a 7/8 inch base, making it a direct fit for standard single- and double-hung window applications. Mounting screws are included.

Installation Notes

Installation is performed by general contractors, window technicians, or qualified maintenance personnel.
