This security deadbolt strike is constructed of stamped stainless steel and it comes in a satin finish. It features a 3/4 in. x 1-1/16 in. bolt opening to accommodate large bolt dimensions. This security strike is designed to replace the smaller deadbolt strike plates with a thicker 1/16 in. plate and two additional fasteners for maximum security. Installation of this strike will strengthen a locked door with the inclusion of two, 3 in. long screws that attach to the jack/trimmer stud to help prevent kick-ins. Some mortising and pilot-hole drilling may be required for a flush install.
