Abstract: A moveable sliding glass door track clip guide, ideally formed of plastic, and attached to the bead on the top of the rail on the sill which is subsequently secured in place by a sliding glass door track clip cover which will inhibit the door from jumping the track in strong wind loads. The guide contributes significantly to the general security of the SGD installation, since SGD's, by design, must be lifted then set upon their track. The guide slidably engages the upper bead on the track on the sill and thus resists the effort of the door to jump off the track by actually gripping the track itself. The method of the present invention involves the steps of first positioning a moveable panel in place. Thereafter, the main attachment screw is removed, and passed through the clip assembly. Only after the track clip guide has been positioned over the bead on the rail.
