Perfect fit for my sliding windows without any damage

We used these on a cooler in a common public area. This really isn’t a lock, it can be removed with an hex wrench. It is useful in our situation because the cooler is used as a reserve for the main cooler. We want people to use the unlocked cooler first, then we reload it with warm soda for cooling and switch the lock over to keep people from getting warm sodas. It just keeps the door from sliding open, it’s not really a security lock with a key. It would also work anywhere it may be placed on the inside, like in a house, where the hex lock cannot be accessed. It can be tightened to the point where it doesn’t slip, doesn’t slide when adequately tightened. Solid product for the right situation.

I don't like this cause u need key to lock the chain, wish it would be automatically locking chain and all u need key is to unlock it, dont recommend

Good but make sure you have enough space to attache.mine was little tight so I could not bracket but made it.

I have a child with autism who sometimes tries to get out of the house when I am not looking. To keep him safe from the second story balcony, I bought a complicated locking system which was so hard to install, I gave up and got this. It works great because it's just a key and a little box. It's sturdy and you don't have to put screw holes in your door. I wish I had found this one first.

i bought it because it’s stainless steel. my door knobs are polished steel and i wanted a chain lock that matched so i got this one for is style. when it came in the chain didn’t match the lock. the chain was dull and the lock was shiny. i was going to return it but decided to see if i could buff out the dull chain to a high polished looked. with a lot of elbow grease i was able to polish it out to a high shine. i shouldn’t of had to do this for something that looked how i expected it to from the advert. pic

My older two became houdinis suddenly. They figured out how to turn down our alarm system so I couldn’t hear them opening the sliding door to go on adventures 🤦🏻‍♀️ (5 and 6). Started putting this on the door after we got it and they stopped with their disappearing acts! Installed it and took the ‘key’ to bed with me so they couldn’t get it and that thing fits so snug they couldn’t make it budge! Finally started being able to sleep better knowing my little Huckleberry Finn and Tom Sawyer couldn’t get out of the house at least 🤣 made me wish my front door was a slider so it was easier to child proof that thing too!!

I didn't have a whole lot of faith in this, but decided to give it a try. Super easy to install, very sturdy, love that it takes a key, and holds tightly! I'd buy more if I need them and I would recommend this to anyone. I use it on our sliding glass door. Just inserted in the track (after rotating the key to get the correct width), tightened up, and voila! No more sneaking out teen!! ;) It also makes me feel extra safe. The door had a lift lock, but I never felt truly comfortable with just that. Always kept a bar in the track, just in case. Now I don't need the bar. This little lock is perfect!!

Es sencillo de colocar. Se sienten buenos los materiales y resistentes en interiores

Bought this for my mom who has my grandma that lives with her and is always trying to close the balcony door so when this is on she has no clue how to close the door on hot summer days definitely worth your money
