First Watch Security's range of patio and window locks is suitable to provide your home with additional security and give you peace of mind when you are away. Some patio doors can be lifted off their track - our anti-lift devices aid to prevent this.

This patio lock is made well. I wish I could install it, but my new apartment complex will not allow me to drill into the frame. I will be giving this to my sister to use on her patio door. I will say it is very well made. The locking peg is sturdy and long, so it will secure the door when I stalled. I really wish I could have installed it on my apartment door, because it would make me feel safer knowing the sliding door could not be easily opened. A great product.. Anonymous. Zephyrhills, FL.
