A sliding door system includes a sliding door having an upper roller assembly disposed atop a portion of the door's frame, a lower wheel assembly disposed at a bottom portion of the frame, a channeled upper track, a lower track having at least one convex longitudinal rail configured to receive the lower wheel assembly, and one or more optional panel divider strips. The lower wheel assembly includes a vertical spine having a transverse shaft coupled to a bottom portion thereof, a lower wheel that has a concave contact surface and is rotatably coupled to the transverse shaft, and a transverse latch member disposed vertically below the lower wheel to slidably latch the lower wheel assembly to the lower track as the lower wheel rotates matingly on the convex longitudinal rail. |
