Becky: They work extremely well I ordered 2 they are difficult to open sometimes but they keep the kids in

Rei L.: This worked on most of my doors except one. The gap between the door and the frame was too narrow and this wouldn't fit. Something to be on the look out for.

Anne alicia: This little piece of strength is amazing. I had my son test push on the door and trying to get through with this closed. He is a 6.4
260 pound weight lifter if he cannot push my door open with this nobody can this is so easy to install. All you need is an electric drill. Mark where you want it make sure the distance opening of your door is not
Narrow or to wide so the product will open and close easily. I bought eight more for every door I have.

TravelSara: Our child has been sleep walking, and last time she was at the front door putting on her shoes! We decided that having locks up high on the door frame would be a wise idea. We chose white, which blends in with our foot frame nicely. The white is not glossy but more of an “eggshell” type finish. Installation was easy and the locks work perfectly. They are simple to use and can be unlocked very quickly in case of emergency. They seem sturdy and well made.

The Moore, Taylor, Wright Families: I recently purchased a door reinforcement lock for my home, and I must say, it has exceeded my expectations in terms of both style and security. This sleek and modern lock not only adds to the decor theme of my home, but it also provides an unparalleled level of protection that gives me peace of mind.

One of the standout features of this lock is its sturdy construction, which ensures that the door remains firmly shut. Unlike some other locks that allow a slight opening of about 2 inches, this door reinforcement lock eliminates any possibility of the door budging even a fraction. This feature is particularly important to me as I have a curious and adventurous 2-year-old who knows how to unlock and open the front door. With this lock in place, I can rest easy knowing that my little one cannot unlatch it and wander outside unsupervised.

Additionally, this lock offers an added layer of safety reassurance for my teenagers, who may occasionally find themselves home alone. The robust build of the lock provides them with a sense of security and peace, knowing that the door is fortified against unauthorized entry. It gives me great comfort to know that my family is protected...
