In a sliding glass door system, having a stationary panel and a movable panel within a door casement, the improvement of incorporating an independent locking system centrally located in the vertical stile of the movable panel remote from the conventional door lock for this panel includes an operating lever mounted in the stile so one end thereof is accessible, a vertical oriented locking bolt connected to the lever for reciprocal movement through manipulation of the lever, and a plurality of apertures in the top track of casement for the movable panel whereby the lever can be manipulated to insert the distal end of vertical locking bolt into selected apertures to lock the panel in selected intermediate positions or to remove the distal end the vertical locking bolt from such apertures to release the panel. In the preferred embodiment the connection of the lever to locking bolt and the bolt are located inside a channel in the associated stile to maintain the aesthetics of the door. Typically the lever is mounted in middle of the associated stile for added safety and convenience.
