The system further includes a plurality of coextensively shaped rectilinear end rails and a mechanism for attaching the support rails to a support surface. The support rail attaching mechanism includes a plurality of coextensively shaped rectilinear beams, a plurality of cotter pins, a plurality of coupling members monolithically formed with the second ends of the shafts, and a rectilinear channel.
