## Overview

The Prime-Line Door Reinforcement Lock is a robust secondary security device designed for swing-in doors, engineered to withstand up to 800 lbs of force.

Easy to install with included hardened screws, it fits most door thicknesses and enhances home or office security with a sleek, professional look.

## Description

Add an extra layer of protection to your home with the Defender Security U 11126 Door Reinforcement Lock. Designed for swing-in doors of virtually any thickness, this high-security lock helps reinforce entry doors and provide increased resistance against forced entry. When properly installed, it is engineered to withstand up to 800 lbs. of force, helping strengthen door security beyond a standard lockset alone. Constructed from durable aluminum with an attractive bronze anodized finish, this reinforcement lock is built for long-lasting performance and reliable daily use. The spring-loaded design functions as a secondary security device that helps prevent doors from being opened from the outside while engaged. It can also help deter lock picking and lock bumping, providing an added level of protection for homes, apartments, dormitories, and rental properties. For added household safety, the lock may be installed higher on the door to help limit access by young children. Installation is quick and straightforward using the included 3 in. hardened screws, though pre-drilling with a 1/8 in. drill bit is required. Some applications may also require mortising for proper fit. Compare dimensions and installation requirements before purchasing to ensure compatibility.
