I installed this lock on a bedroom sliding closet doors. Installed to lock valuable antiques stored in closet to prevent guests from gaining access to these valuable items. The home is used in a "swap vacation" situation, where owner travels and makes home available to others during a vacancy period. Locks sliding doors the same as an exterior sliding glass door. Easy to install.

This little lock worked great on my back door screen. Looking to replace the one I had but could not find it anywhere. I was so glad I came across this one. It’s better than the first.
