4 Pc Sliding Window Lock

They do the job, although they can get loosened sometimes and can get pushed to the side by opening the window. So I have to check them once in a while to make sure they're tight. I use one on the top rail if the window and one on the bottom. Just one by itself wouldn't be strong enough. Now I don't have to worry about my toddlers escaping outside or risk them falling out of the second story windows.

This will just not lock onto yet aluminium track on my sliding windows, tightening just pushes it up away from the track. It may be the slanted angle of them. If you do manage to get them on they loosen up with one touch.ive seen some on here that ars straighter, which may work better.

I,bought the four pack of these windows locks,i,have use these before is a mobile home,they work,!!!!! if you want the extra added tightness use ,pliers to make sure that they stay in place,.other than that ,they are worth the money.

There ok. If you try to tighten them to tight they slide off ( as in they don't stay put 100%)

I bought these to keep my toddler from opening his bedroom window.These are small, lightweight, and will strip easily.I am keeping them because they were cheap and will keep my toddler from escaping. If you are looking for a lock to keep an adult from opening a window, keep looking and invest in the bigger ones.

Great product great quality

You can't go wrong with these locks. I live in an apartment.

Stops the slider and the window from being opened.
