Product Description
Add an extra layer of protection to your home with the Defender Security U 11449 Door Reinforcement Lock. Designed for swing-in doors of virtually any thickness, this high-security lock helps reinforce entry doors and provide additional 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 a matte black finish, this reinforcement lock features a spring-loaded, tamper-resistant design that helps prevent doors from being opened from the outside while engaged. It can also help deter lock picking and lock bumping by serving as a secondary security device. For homes with children, the lock may be mounted higher on the door to help limit access and improve safety. Installation is quick and easy with the included 3 in. hardened screws, making it an ideal DIY security upgrade. Pre-drilling with a 1/8 in. drill bit is required, and some applications may require mortising for proper fit. Whether used in homes, apartments, dorms, or rental properties, this reinforcement lock provides dependable security and peace of mind without replacing existing door hardware
