Terrible didn’t work for me
Terrible, didn’t work to secure the sliding windows, then straight into bin unfortunately. Don’t recommend

Very strong
Great for stopping lower sash from being raised but obviously doesn't stop upper ( rear) sash being lowered! Still looking for a solution to this which doesn't involve drilling into the frame.

Sturdy window locks
Easy to use and worked perfectly on my new vinyl windows. Windows are secure and don’t move. Would purchase these again.

No-Damage window locks great for vinyl frames.
Perfect for controlling and securing the windows. They came assembled and ready to use. The cam-lock was especially intuitive for a cyclist as they are much like my front and rear axles. I know how I trust my wheels to stay put so do I trust these quality cam-locks to perform. Great product and will recommend to family and friends. Thank you Prime Line Products!
