ABSTRACT:
A collapsible support is provided for supporting carpentry work, boards, roadside annunciators and the like. The support is equipped with downwardly divergent and telescoping legs, for height adjustment, that are united to a horizontal beam or stringer by means of 3-way brackets. A pair of leg braces are provided to limit leg spread, afford additional support to each pair of legs and also support a carrying case. When the support apparatus of this invention is disassembled it may be positioned inside the carrying case for compact storage or transporting about.
