2 Pack Sliding Door Safety Lock - Child Proof Window & Patio Door Lock, No Drill Easy Install, Baby Safety Guard Lock for Closet & Windows

The locks were of high quality and secured the sliding doors so that my Autistic Grandaughters whom general figure out how to remove or break the plastic ones are safe. The were easy to install and a good value for the money. My daughter could easily remove with the key. But they performed well to keep my grandchildren safe.

Great product! Easy to install and uninstall. Kept a 3 and 5 year old from getting out near the pool. No adhesive or climbing on ladders. Simple, works and reasonably priced. What else can we ask for in a product?

Bought these for my windows because they are older and needed a bigger grip. Well they work. It locks the window right in...no pushing it up.👏👏👍

These are useless they don't work. You tighten them they loosen. Absolutely no security at all

They work really well, very strong unable to open sliding door. Excellent

Trying to keep person with dementia & Alzheimers inside of the house. One of the sliders has railing that this can be tighten to. One of the sliders is 40 years old and had no raiis to tighten this item to. So the item only works if it is fully opened. Which is the opposite of it's design. These will help keep the sliders closed. They maybe kicked loose by person inside of house that wants out. These items would keep the door from sliding from the outside. So if trying to keep burglars out of the house they work.

I think someone tried to get in the sliding door. This item has been a great help and I feel a little more secure.

Works but did overnite delivery and received it over a week later
