Track system for sliding door

A track system kit which can be used for hanging a sliding door, comprising:

• (a) at least two channel sections which each include a bottom wall and two substantially parallel sidewalls which extend upwardly from the bottom wall and which when placed end-to-end form a channel;
• (b) at least two tube sections which each have a select outside diameter such that said tube sections can be positioned on the bottom walls of the channel sections, and at least one hollow end with a select inside diameter;
• (c) at least one spacer which each includes a central cylindrical portion with an outside diameter equal to the select outside diameter of the tube sections, and two cylindrical insert portions which each have an outside diameter substantially equal to the inside diameter of the tube section hollow ends and which each extends axially from one of two ends of the central cylindrical portion and can be inserted into one hollow end of said tube sections, so that the tube section end abuts against the corresponding end of the central cylindrical portion, and outside surfaces of the tube sections and central cylindrical portions together form a substantially smooth, continuous cylindrical surface;
• and
• (d) at least one bracket including a vertical leg which can be connected above a doorway, and a horizontal leg which extends outwardly from the vertical leg so that when said kit is assembled, the horizontal leg will adjacently underlie the channel bottom wall.
