ABSTRACT:
Support apparatus includes a pair of folding leg elements pivotally secured to a longitudinal beam assembly. The beam assembly includes two beams longitudinally aligned with each other and secured by a U-shaped clamp. The leg elements are secured to the center, longitudinally extending beams by a pair of cam lock units, secured to the leg units. The cam lock units pivot and are lockable to the beam in both the open, support position and in the folded, storage position. The use of the two beam elements and the U-shaped channel connector allows the beam elements to twist relative to each other, and the twisting allows the leg elements to remain stable while disposed on an uneven surface.
