A sliding door/window track assembly particularly suited for use with thick glass. Fastenable directly to both the upper and lower edges of such glass, the assembly includes a frame member made of plastic. The frame member is suspended between a pair of guides formed within a track member. A plurality of keys, which ride in slots formed in the sides of the guides, are employed not only to suspend the frame member but also to lock it into the track member for security. Moreover, the track member also allows a large amount of foreign material to be deposited along the track before any interference with operation occurs. Further, the track assembly can be fabricated so that only plastic material rubs on plastic when the door/window is slid, thereby allowing for free movement with little friction.
