Abstract
Abstract One or more adjustable retainers are mounted on top of a sliding glass door at the corners, or suitably spaced, to fill in the space between the sliding glass door and the inside of the upper track so that the sliding glass door cannot be lifted vertically from the outside by unauthorized persons. The fastener comprises two adjustable wedge members which are secured to the door or the track.
