CZU Home Door Lock Security, Upgraded Safety Childproof Door Reinforcement Lock Latch (2-Pack), Extra Defend Door Lock for Inward Swinging Door

I have had these locks on double doors for a couple of years now. They are still fantastic and every time I unlock them I think about how happy I am that I got them. Easy to install, VERY secure, even for double doors!!! I would say they are the only way to go with double doors! I highly recommend these.

Gives security to your home. Easy to install and gives value to money. Holds the door well.

I used longer screws but I love 💕 the locks very functional and easy to install and use. I feel like my lil toddler is safer and i don’t have to worry about her running outside without me knowing.

Nice and sturdy, but I could not use it in my specific case. It appeared to be sturdy and the installation was the same as the other similar products. Once installed correctly it would be secure, but unfortunately it wasn't;t going to work in my specific case. This is a great product for protection from somebody trying to break into your residence/business. It is not so great when you are trying to prevent a person (child or at risk adult) from leaving the premises.

Good product

I like the overall quality of them, but the set screws moved while installed causing it to not slide any longer making me to have to buy stubby Allen Wrenches to jimmy in there and adjust them (I would rather not remove them as that would compromise the security of the initial wood screw installation). I wish you would have mentioned something like this being a problem, that way I could have loctited the set screws.

I recently installed a set of CZU Security latches on both the front and back doors of my daughter’s home. Last Saturday morning, someone attempted to kick in her door, and while the doorframe around the deadbolt and latch was completely split, the CZU latch held strong. The intruder wasn’t able to break through. Although I hate that we had to put the device to a real-world test, I’m incredibly grateful it worked – my daughter is safe because the CZU latch didn’t fail.

Just finished installing the security lock. Follow directions and you will get a good security system for your door. Very easy to use, just slide lever to left to lock and to right unlock. Easy as that. A really great product to secure your door from unwanted intruders.
