[57] ABSTRACT
A collapsible sawhorse unit that, when unfolded and combined with a replaceable crosspiece, produces a sturdy and economical sawhorse. The unit includes the two A-shaped end pieces, of two legs each, that fold toward each other with the legs of each end piece folding toward each other. A folding upper longitudinal brace joins upper ends of the end pieces, and a pair of lower folding longitudinal braces joins the end pieces proximate a mid-point. Folding transverse braces of each end piece provide rigid separation of legs during use such that upper ends of the legs clamp against the replaceable crosspiece. Components of the folding unit are typically fabricated from standard metal stock. The resultant folding unit occupies a minimum volume, when folded, for convenient transport to a construction site.
