The Cal Double Bolt sliding glass door lock prevents the door from being lifted off the tracks by securing the door with two bolts. One from the top of the latch and one from the bottom. This is one of the best ways to secure that sliding glass door.

Child Safety Feature

We started installing the Cal Double Bolt Locks when they first arrived on the market about 10 years ago. Up until that time, we were installing Charlie bars for arcadia door security.

Charlie bars are a great step above throwing a wood dowel in the window track. They secure to the slider and then folded down and locked into place on the frame side so that the sliding glass door cannot be opened.

But, Charlie bars are not ideal. While the door was firmly held shut by a Charlie bar, the door could still be lifted out of its tracks with a screw driver and they are pretty ugly.
