1 Pack Sliding Patio Door Foot Kick Lock, A Secondary Childproof Additional Security, Universal Fits for Any Sliding Door and Window Top or Bottom Rails, White

We installed these on our screen door. We have a cat that figured out how to open the screen and escape and this took care of that problem.

Fácil de instalar y súper segura

Unfortunately, the lock on my sliding door failed. And I was having a hard time finding a replacement, but in the meantime, I still needed a way to lock the sliding door. So when I saw this, I jumped right on it.It installs very quickly and easily you just have to be careful about screw placement because you don't wanna interfere with the door sliding.It works very easily. You just push down on the button which engages the lock. And there is a release button on the side you just tap with your foot and it unlocks. Once the Lock is engaged, there is no opening the door.There are two positions for the lock one is when the door is completely shut and the other you can open it about 3 inches and engage the lock if you just wanted to let some air in the house but still keep the door locked.Overall, I am very happy with this Lock. It's strong, secure and installs easily.
