• b. a plurality of rods each of which is transversely disposed across said sleeve passageway and within said pair of oppositely-disposed apertures in said sleeve wall and projecting therebeyond and further being fixedly secured to said sleeve wall disposed about said apertures;
• c. a second flange, said second flange rimming said rear portion and extending outwardly in a substantially radial fashion therefrom and having at least four openings therethrough, said openings being adjacently disposed to the corners of said rectangularly-shaped sleeve passageway;
• and
• d. at least four tubular members, one open end of each of said members being fixedly secured about one of said openings in said second flange of said sleeve, each of said members being also fixedly secured to said sleeve and disposed in parallel relationship to the longitudinal axis of each of said four corners of said rectangularly-shaped passageway of said sleeve.
