Charley Bar for Locking Sliders

Charley Bars for Patio Pet Doors in Sliding Glass Doors

One very nice solution is to use a "Charley Bar" like the one at right. It is adjustable in length, sturdy and is mounted about half way up the jamb behind the sliding door. When it is positioned against the sliding door, the sliding door cannot be opened.

Of course, for the Charley Bar to work, your sliding door must be on the inside track.

You'll find a "Charley Bar" available at "Flaps & Parts"
