Prime-Line Door Reinforcement reinforces deadbolt and key-in-knob locks by more than doubling the strength of the door at critical stress points. Crafted from heavy-gauge metal with a solid one-piece construction, it provides robust protection against kick-in attacks. This product is designed to enhance the security of your door, although the deadbolt is not included. It features a polished brass finish and is available for doors with thicknesses of 1-3/8" or 1-3/4". Each package contains one unit and is packaged in a clamshell for easy handling.
