ABSTRACT:
A support structure adapted for facilitated assembly. The support structure includes a base portion in the general configuration of a sawhorse having spaced horizontal sideboards secured to angled legs at opposite ends thereof in recesses provided in the upper end portions of the legs. Bolts are provided for securing the sideboards to the legs and maintaining the upper end portions of the legs in locked abutting relationship. The outer edges of the upper end portions of the legs are received in slots on the inner surfaces of the sideboards for further improved rigidity of the support structure. Different upper extensions are provided, with adjustable clamping structure for permitting variable height of horizontal supports carried on the upper end of upright portions thereof. A ladder is removably associated with the support.
