  • the lower engagement portion is sized such that small gaps are present between the engagement surfaces 462 of the lower engagement portion and the lower engagement surfaces 322 of the two adjacent rails. Accordingly, the notched attachment rail may be moved longitudinally within the channel to position the notched attachment rail at a selected location within the channel. For example, in FIG. 17 , the notched attachment rail is positioned with a portion of the notched attachment rail extending forward beyond the front edge of the first enclosure shell.
