Window Locks, 10 Pack for Vertical and Horizontal Windows, Sliding Window Locks, Adjustable Aluminum Stoppers, No-Drill Install, Fits Tracks up to 3/16" Wide

These work well an are easy to install. In my case, the rubber made it a little too narrow to fit on my window frame, but no problem installing with the rubber removed.

My apartment windows did not include locks and since I am on the bottom floor, I desperately needed to find a solution. I found these and they do not budge when I try to open my windows. I love the extra peace of mind these provide to me.

We bought these to limit the opening of our windows because we have young kids. It might be a little “overkill” as I do not think my kids will open a window and jump out but it is always better to be safe than sorry. Use: It does a great job of what it is supposed to do. The black rubber prevents scratching the surface of the window. It took us less than a minute to install them. It is so easy, it can even be done with one hand (see my video) Pro(s): - Very easy install - The grip is tight and does not easily come off Con(s): - Does not look the best - Although the black rubber prevents scratches on the front facing surface of the window frame, it does not prevent scratches on the side of the sliding window Tip(s): - If you leave a little rubber extended of where the sliding window will be hitting this stopper, it will help cushion it and prevent scratches

These window locks are great for keeping unwanted guests from entering my house!

Work perfectly on our windows, this was the economical solution we were looking for.

Aluminum part is good but rubber pad is too small for windows. Weight is light.

For the price of these 10 window locks you can't go wrong with this product. I've seen similar products that proclaim similar features but are smaller in size, only have one screw for security and come with a fewer number of actual locks in the package. Installation is pretty self explanatory, straight forward and simple to complete. The product is constructed of all aluminum that feels sturdy with a foam strip of cushion along the edge wear it contacts your window. The design is simple and easy to understand. Once in place and securely tightened they effectively prevent the window from being raised past your specified height or not raised at all. They are as easy to remove as they are to install, simply unscrew the fasteners and remove from the window track. I installed one on every window in my house, even on my windows with locks that were still functional just for added security and peace of mind. Shop around and look at all the different choices but rest assured you can't go wrong with this product if you want a simple solution.

Great product but unfortunately they didn’t fit the windows in which they were intended for. However , they were still put to good use. Durable, and gave me a peace of mind knowing my littles will be safe.
