ABSTRACT:
An improved collapsible sawhorse package in which each pair of legs of the sawhorse are interleaved with the ridge board placed centrally therebetween. When formed into the package, the ridge board and one leg of the opposite pair of legs are positioned between the two legs of the other pair and within the ridge board gripping bracket mounted to that other pair. A securing pin extends through the package formed by the interleaved pairs of legs and the ridge board and is secured in place at each end by rods which extend through the ends of that securing pin. The rods are also used to maintain the pairs of legs open when the sawhorse is erected.
