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. ## Features - KEEP YOUR HOME SAFE – Designed to withstand 800 lbs. of force, this U 11126 bronze finish door reinforcement lock helps to prevent doors from being kicked in, increasing your home security and keeping you and your family safe! - EASY INSTALLATION – The included 3” hardened screws make installation a breeze – extra security and peace of mind can be achieved in just minutes! - ADDITIONAL HOME SECURITY - Use this bronze finish high security door reinforcement lock for additional home security on any swing-in door of any door thickness.
