Abstract
The device locks the sliding panel against horizontal and vertical movement. The device is secured on one of the upraised walls of the panel track by an eccentric that works in opposition to a support flange. The support flange carries slide stops to prevent the panel from sliding in its track. The vertical movement of the window out of the track is prevented by a lift stop comprising a flat spring secured in the upper track or lift stop elements on the support flange.
