ABSTRACT:
A lightweight sawhorse which may be easily collapsed in three transversely aligned directions to form a compact, portable package and thereby facilitate the transport and storage thereof. The dimensions of the sawhorse may also be selectively adjusted to adapt the sawhorse to be used at a variety of job sites and supported upon an irregular or non-planar surface. More particularly, the respective lengths of each of the legs of the sawhorse may be adjusted independently of one another. Moreover, the length of the cross member which extends between opposing pairs of the sawhorse legs may also be adjusted. What is more, each of the sawhorse legs may be rotated independently of one another through an arc between a generally vertical position to a generally horizontal position below the cross member.
