ABSTRACT:
A saw horse includes leg support members that have top and bottom portions, and planar front and rear surfaces. The top portions have a notch formed therein. Coextensive support arms are pivotally connected to the leg support members. Each support arm has a top and bottom edge, and is adaptable between folded and unfolded positions. A first support beam is removably positionable into the notch, extending downwardly. The first support beam has opposed end portions situated away from the leg support members and has a major longitudinal length thereof horizontally intercalated between the leg support members. A second support beam is removably positional in the notch and has a bottom surface engaged with the first support beam, defining a work surface. Rubber pads are engaged with the bottom portions of the leg support members, assisting to maintain the saw horse at a stable position during operating conditions.
