  • Added comfort of additional security

The primary purpose of this lock reinforcement is to provide an additional layer of protection for your front door. The 3" stop, capable of withstanding 800 lbs of force, adds robustness to your existing door lock, making it significantly more resistant to forced entry. As a result, I feel much more secure knowing that my home is better protected against potential intruders. However, one of the standout features of this security lock is its childproof design. With its inward swinging flip lock mechanism, it prevents children from unlocking the door and wandering outside without supervision. As a parent, this added level of protection and peace of mind is invaluable. Installation was a breeze, thanks to the detailed instructions provided. The lock reinforcement is designed to be easily installed on most inward swinging doors, whether they are wooden or metal. No special tools or expertise are required, and it only takes a few minutes to secure the lock in place. The durability and reliability of this door reinforcement are commendable. It is made from sturdy and high-quality materials, ensuring long-lasting performance and effectiveness. Additionally, its sleek and unobtrusive design seamlessly blends with any door, maintaining the aesthetic appeal of your home while enhancing security.

This broadens its scope of use and ensures consistent security throughout your living space. Overall, the Home Security Door Lock Reinforcement is a wise investment for anyone looking to enhance home security and child safety.

  • Super easy to install and use!!
Color Name: White
This was super simple to install. I didn’t even have to drill pilot holes. It took me about two minutes total to install it. It seems very sturdy and well made. The entrance to our upstairs bonus room is through our 10 year old’s bedroom, which is understandably creepy to her sometimes at night, and this makes her feel much more safe and secure. She has no problems using it. Highly recommended!! ... show more

  • STURDY!
Color Name: Black
This thing is extremely sturdy!!! We bought it because we wanted extra security for if our electric doorknob malfunctioned while we were out, we have peace of mind that no one can get in! We’ve tried “busting in” so to speak when the lock is active and it holds steady!!! It was easy to install and you can choose what part of the door you hook it on, we did it near the top so a child could not reach up and unhook it. It’s very easy to use and is very discrete on the door. ... show more

  • Great while it lasted, but second pair was backup
Color Name: Silver
This lock is pretty awesome. Quick install, easy to use, and very sturdy. So sturdy, the wife locked me out a few times and the door doesn’t budge. Only downfall was it lasted just about 9 months installed. It started out smooth, but then at about 3-4 months in, it started to get rough swinging the latch to lock it. Today, it locked up like the spring inside broke and it won’t lock all the way. Had to take another tool to pry it open. Good news is that it came with a pair of locks. I just swapped it out and we’re back in business. I’d still buy it again for $10 for a pair. ... show more

  • Easy Install and Exceptional Use
Color Name: Black
I was shocked at how easy this was to install and yet how strong it is. Minus kicking down the door we stress tested it and it can hold my body weight (over 150 lbs) so it's securely on our door frame. Was also surprised at how easy it is to use. The spring action on the hinge is very nice and honestly we want to get more of them for other doors in our home. Great purchase. ... show more
