Review on Ensure Ultimate Door Security With Door Reinforcement Lock – Child Safety 4 Screw Lock For Inward Swinging Doors by Marvin Breezy

This took under 20 minutes to install, including shaving down the door frame to accommodate the lock. I put one on another door that had more space between the door and the frame, thus it didn’t need any adjustments, and that one took 3 minutes. This is a solid backup lock, which makes it almost impossible for someone even with keys to open the door when the lock is engaged. Great for use at night, and on all but one entry to your house when you are away (since you can only engage from inside, and you wouldn’t want to lock yourself out). No one will be able to shoulder or kick open the door, and even if the keyed locks are picked, this one will keep your door securely shut and prevent entry. Solid buy!
