Sliding Glass Door Child Lock - OKEFAN 4 Pack Baby Safety Slide Window Locks for Kids Proof Patio Closet Doors No Drilling Tools Needed (Blue)

Gives extra piece of mind knowing all windows and sliding doors are extra secure at night. Easy to install and operate.

Works easily to block both our slider and screen slider from being opened.

Works great for the back sliding door.

I actually use them for an extra security for my sliding glass doors. It gives me more piece of mind. They are easy to put up.

These 100% work!! ESPECIALLY if you have toddlers. My almost 3 year old tries to go outside by herself and although we have a fence she went outside by herself when we were sleeping and scared us so I immediately bought this.
