The adjustable saw horse according to the present invention has a wooden cross beam securely attached within a U-shaped aluminum channel which extends for substantially the length of the wooden cross beam. The cross beam has two supports, one at each longitudinal end of the cross beam, each support having an A-frame shape as the saw horse beam is viewed from an end. Each support consists of a pair of telescoping legs pivotally mounted to brackets on the sides of the aluminum channel, and a brace which is adjustable in length between the pair of legs. Each leg is hollow, tubular, and square in cross section. Each leg has a foot pivotally mounted thereon, the foot having a serrated edge adapted for penetrating the ground in order to firmly anchor the saw horse on sloping ground. The height of the saw horse may be adjusted between thirty-six and seventy-two inches. The saw horse is appropriate for use as a small scaffolding as well as a trestle for general carpentry work.
