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.

These sliding patio door locks are keyed for extra security and help prevent unwanted opening of patio sliding doors from either side. The durable housings of these locks are constructed of diecast metal and they feature solid steel locking bolts that extend, retract, and lock into place. The security benefits of these socks help to prevent prying and lifting of the active panels, significantly reducing the chances of entry from the outside. Each set includes two sets of keys, installation hardware, and instructions, and they can be installed with a few simple tools.
