## Description

Overview Add an extra layer of security to your home with this Defender Security Door Reinforcement Lock. Designed to withstand 800 lbs. of force, you can rest easy knowing your family is safe and protected! This reinforcement lock has a spring-loaded design, aluminum construction and a satin nickel anodized finish. This reinforcement lock can be quickly and easily installed on any swing-in door of any thickness, and can help ensure the door cannot be opened from the outside by being kicked in. Additionally, it’s tamper-resistant, so it can protect against lock picking and bumping. Plus, it’s child-safe, because you can install it higher on a door, where your young ones can’t reach. Length is 2 to 0.19 inch. Width is 1 to 0.38 inch. Installation takes minutes, and the U 10827 door reinforcement lock comes with 3” hardened screws. Extra home security and peace of mind are well within reach - and doesn’t have to come with the high price tag of an alarm system! This high security door lock meets the Texas building code requirements. Be sure to view the manufacturer’s How-To Installation Video also linked to this page, in the upper left-hand corner.
