  • efficient for the price payed
These chain locks were ordered to give some security without having actual locks on the doors. They arrived promptly, and I was able to set them up without too much effort, and they are doing their job well.

  • Great for my use.
I installed this on a patio door so the door could be cracked open but still secured. By moving the slide part higher than the lock I was able to make it so an outsider could not reach in and slide the chain up far enough to unlock it. I can still open the door about 5 inches. It worked out great! It seems to be good quality material and matches other hardware on the door. ... show more

  • This item broke after only a few months of use. The metal has some weak points it seems.
