ABSTRACT:
A door track adapted for carrying a trolley supporting a door for rolling movement. The door track includes one or more single-piece track members having a first substantially planar surface and a pair of substantially identical spaced apart portions extending from the first substantially planar surface and forming a channel with the first planar surface. The spaced apart portions each have a substantially planar portion adjacent the first substantially planar surface to provide a plurality of flat mounting surfaces. The spaced apart portions further include inwardly curved portions extending from the substantially planar portions which are adapted to support a trolley for rolling movement therealong. The inwardly curved portions are spaced apart to freely receive a door supporting member which is secured to the trolley. The track member may also include lip portions extending outwardly from the curved portions, and the substantially planar portions may define fastener receiving openings for bracket-less mounting of the track member to a supporting surface. With this construction, a self-cleaning, self-centering door track having integral mounting structure is provided.
