A first coupling is positioned at the first end has an outwardly extending portion extending outwardly from the first end adjacent to the second face, an angled portion extending from a remote end of the outwardly extending portion toward but not past the first face, and an inwardly extending retaining lip extending from a remote end of the angled portion back toward the first end. A second coupling is positioned at the second end is similarly configured with an outwardly extending portion extending outwardly from the second end adjacent to the first face, an angled portion and an inwardly extending retaining lip.
