Simple and secure for basement windows
This window lock is simple and effective. I installed it on my basement window for extra security. The thumb turn screw keeps it secure, and it can be used closed or slightly open for ventilation. Installation was easy with no tools required. Overall, a practical addition for added peace of mind.

Little but strong and powerful window locks
These things are small but work incredibly well. Once you put them on they don't budge! They only way to open the window is to unscrew it. It works on my side sliding and up and down sliding windows. Excellent security for very little cost.

Very sturdy, and easy to use.
I needed to replace my old slide stoppers. I was pleased with how they were quick and easy to swap out the old and swap in these new. These were affordable and they are doing a great job.

Amazing!
I love these because they actually work, I was a bit skeptical when I received them because they seem so small and lightweight, but to my surprise they work better than anything else!

feel safer
I use a stick in my sliding glass door to keep anyone from breaking in but sometimes I need the air and want it open a little bit when I'm home. These are perfect for me to keep the door open only about 12' and still keeping it secure. I didn't want to go back to the home improvement store and have another stick cut to the size I need. Perfect for all windows

100% Happy with the purchase!
Easy to use and they work perfectly! I don’t know about damage. I just put them on and don’t plan to take them off. Good quality. The white is nice. I’d definitely purchase again!
