The support assembly further includes first and second fixing members each having internal threads which compliment the threads on the threaded rods. An elongated rigid support member having first and second ends, first and second lateral sides and top and bottom surfaces is provided. The support member includes a first notch in the top surface at a second predetermined distance from the first end, the first notch being sized for receiving the first fixing member therein. A first bore extends from the first end toward the second end, the first bore being located a third predetermined distance from the top surface and intersecting the first notch, the first bore being sized for receiving the first threaded rod.
