Sliding Window Lock with Key, Security Window Locks for Up and Down Window Horizontal Sliding Window Safety, Child Proof Sliding Door Lock Bar Vertical Stopper Easy Installation (8, Silver, Standard)

Great product!

The lock worked exactly as it was supposed to work. Very easy to install and sturdy. Based on the reviews, I was unsure if the lock would work on my large sliding door. But the lock fits easily in the sliding door track. Once tightened, the door wouldn't move at all. I recommend them.

Great product .. I replaced some smaller locks with these because they weren’t wide enough to clasp the window and glad it did these are slot stronger and thicker metal. Using o. Sliding 65 “ high windows , and they work

Didn’t fit in my sliding door, the edge on door frame is too thick and curved. However I was able to use it at windows, and it works well. It’s not something you want to open and close all the time, too much work, but definitely feels secure to have it on the windows more permanently. I set it so I can open windows, but only a little bit. You get a heck of a value in the box, 8 locks, and keys for each lock! I also wish they came in white, as my window frames are white. Why black only? Anyways, if you are lucky and they fit, they are great.

It blocks the open window from opening any wider then you want. I used them to lock fans in my lower level and I have no worry about being forced open. The white color blends in with my white frames are are not really noticed.

Sugiero revisar muy bien el diseño y dimensiones del marco de todas las ventanas dado que no siempre encaja en todos los diseños.aun así pude acomodarlos y me siento más seguro

Easy to do and use,works wonderful and is sturdy!!! Used to secure and lock sliding patio doors.Thank you!!! Would recimmend.
