Window Locks, 4 Sets Sliding Security Window Lock with Key for Vertical & Horizontal Sliding Windows & Sliding Doors, Adjustable Window Locks Security Window Stoppers for Patio Bedroom Home and Office

My kid got one of the windows in his room out of it’s track. He had to also break a latch off the window to get to where he could remove the window. It’s a miracle the glass didn’t break. I don’t know how he was able to break the latch and I couldn’t get it back on of course.You may be wondering why I didn’t stop him from doing it in the first place. I was watching the Vikings paste the Giants in New York, even though the stadium is in East Rutherford New Jersey. Go Vikings.Now that he knows how to take it out I had to immobilize the window somehow. The short term solution was to use a vice grip to jam the window closed. Does the kid know how to use a vice grip? No, but I bet he can figure it out! Long term solution is these clamps. They come with Allen wrenches with wings that make instillation super easy. He watched me do it so as long as I keep the wrenches away from him he 𝑝𝑟𝑜𝑏𝑎𝑏𝑙𝑦 can’t get the window out again. I think it’s worth noting that this same child once pulled a doorknob off a door without removing the screws. Seriously. The doorknob was in another room but the screws that hold it in place were still in the door. At least he didn’t lose anything we needed to put it back together.This product served my purpose very well. There is foam on the inside to prevent metal on metal contact but once tightened it stays securely in place. For my situation these were worth every penny.

Strong, well made locking device. Installed on vertical opening ground floor bedroom windows. Able to leave the windows cracked open at night without concern an intruder could force the window open. Easy installation with the included Allen key. Rubber insert assures no damage is done to the window track.

Simple design, required no alterations-couldn't have been easier to install. The provided keys allow for quick removal. The locks are secure and hardly noticeable in the window.

Easy to use. Fits perfectly on my windows

This worked like a charm. After installing a portable A/C, my wife wanted a piece of mind to prevent anyone from opening the window from the outside om being open and these window locks gave that to her. I installed one at each side. The installation was very easy!

So easy to place on window love how easy to remove when you need to open window. I feel safer with placing on every window, the quality and design is so functional for your money spent.

Fit my windows perfectly

Not the only protection.
