Works great on metal framed horizontal sliding windows. Mounting of these locks are on the frame (fin) of the sill, tightly against the window frame itself. Screw down the lock as tightly as possible to the fin on the sill. It works by blocking the sliding window from sliding open.I removed 1 star because the screws on these are a bit too short. So if your frame fin isn't at least 1/8" thick, the screw wont be long enough to tighten on the frame. Be sure to push the block up against the sliding part of the window as close as possible. And tighten the screw as tight as you can by hand. The screw digs into the metal sill a bit to hold it in place. It's usually best if you screw one down on the top and bottom of the sill as this will keep the window tightly closed and unmovable. That also works great where kids can't reach the top one to remove it.You should only use these on sturdy metal window frames and sills that have metal fins sticking up to hold the window pane and frame in place so it can't slide. They mount on the sill not the actual window. You can also put a measured piece of wood in the window slide track or from the sill to the window frame, further securing a sliding window from being opened.You should not buy these blocks if you have plastic sills or frames. The screw can crack plastic if too tight and just slide off if not tight enough. These are made to dig into metal sills and frames only. If they are in the direct sun, they could melt into your plastic sill. They are not made for plastic.A burglar with a lot of time and an out of site location might eventually be able to pry your window and screen off to get around these. Or they could just break the window. But they would risk a lot of attention and make noise doing it. Most burglars don't want to waste time or risk detection by fidgeting and prying and would rather choose an easier to slide open window or your neighbor's unprotected ones. Your best burglary defense is always an alarm or vigilance. These are just used as a measure to not make it easy to quietly push a sliding window open.These can also be used to keep small children or pets from opening and falling out of windows. By having one on both the top and bottom sill, tightly screwed down, small children can't reach the top block.Another feature of these is to quiet horizontal sliding windows that loosely bump and rattle when wind blows on them. When used on the top and bottom of a loose fitting, closed sliding window, these can hold that window tightly to the sill, stopping the window from bumping and moving.I have several windows that have these installed on both top and bottom. They serve their purpose well.

They work. I'm reviewing this because Amazon promised to tell me a joke for reviewing 6 items. Like the fool I am, I started reviewing items, and after each it was like "5 to go", "4 to go", etc until 2. Now it's no longer offering to tell me a joke. The joke is me. And it worked, because here I am leaving a review for window locks despite the lack of a reward now. But I digress... The window locks were exactly what I was expecting, I needed to lock some windows with portable ACs and we have the pretty standard plastic window frames that these clamp down on. If you're the kind of person who keeps and immaculately clean white tiled house with white furniture, you probably don't want these ones and they will leave a small mark on your window frames. However you probably don't need window ACs at that point...

These don’t work for security. A bump to the window and they move no matter how tight you put them on. You can use two side my side which improves but as they are designed no extra security to house

I already had 6 similar window locks that I used on our windows when on holidays.Bought the extra ones so I had enough for all our windows and sliding doors.It is such a simple product but works perfectly. Makes it almost impossible to open the windows or sliding doors from the outside.They are easy to put on before you leave and take off again when you get back home.

Very good service and the window locks replace older fitted locks that damaged the window frame. So far, so good.

they seem sturdy enough, I guess. I can't get them on my windows though. I live in a brand-new house so I thought they would work fine on new windows, but they don't. maybe there is a trick that isn't obvious...really how hard should this be to put them on.

5 years ago, I purchased some similar devises made with some sort of polyvinyl or plastic. They worked perfectly. They went missing in a move. Now, living in a ground floor apartment, I purchased these aluminum devises, thinking metal would be an even stronger block. Wrong! After tightening them as tightly as possible by hand, they simply slipped off when I put a little force on the window. Trying again, I used pliers to get those little suckers to hold. The bolts really dug into the vinyl frame. Nope!! Same thing happened. They popped loose! I think the problem is in the material itself. With my first set that worked so well, the material was more flexible. Screwing them on caused the entire devise to bend just enough that was pressure exerted all along and around the clamping devise. The entire surface of the clamp grabbed tightly against the window frame. With this second metal batch, there was little to no flexibility. In places, the clamp didn’t even touch the window frame. As a result, only the bolt truly gripped the frame. The surface area that gripped was so small, that movement against the window was sufficient to loosen the bolt, releasing the whole clamp. I taped a couple of wooden dowel rods into the window tracks as a stop-gap measure. They aren’t pretty, but they should work until I can order some vinyl clamps. My advise: save your $$; skip the metal ones because flexibility is better!
