Abstract
Configured to resemble a classic sawhorse the invention is formed of rectangular metal tubes and "I" beams that are attached to and contained within a main beam. Side mounted tubes swing out and extend tubular members contained within them. "I" beams extend from the main beam and extend channel beams transverse to the longitudinal axis. Through a series of holes and pins the beam extensions and the supporting legs are adjustable over a wide range.
