Sliding Glass Door Lock for Home Safety - 4 Pack Sliding Patio Door Locks, Child Safety Slide Window Stopper, Extra Strong Adhesive

I bought this since my toddler started opening the door. You can’t see it from the outside unless you pay close attention. Great for childproofing.

Great value for the money. My son kept escaping on the porch, so I had to find a solution. These worked great. Installation was very easy

So easy! Works great!

So easy to use- and they work!

I have searched everywhere for these since I went to Florida and that's what most Florida rentals use and finally found them and I've installed them on all my windows. Very durable and sticky

I love these locks, I have used them before and it works great! I have double sliders so I put two on each side, I found that they work best if you put it as close to the door as possible not giving any space for someone to be able to slam it off

Doesn't have clearance for door to slide past, just a little force has the unit snap at the hinge. This thing is total junk.Adhesive was nice though, huge pain to get the lock off my window.

Exactly what I needed. We recently got a sliding glass pret door insert and needed something to hold the door closed
