ABSTRACT:
A portable, lightweight, board-gripping support for a conventional board includes four rectangular, tubular pieces. The four pieces are configured and connected to form generally an A-shape in a single plane. Bar members form the upper and lower cross members of the A-shaped support. Opposing surfaces of the bar members are substantially planar, oriented orthogonal to the plane of the A-shaped support, and spaced apart by a distance greater than the thickness of the board such that the support forms an obtuse angle .beta. with the board when the edges of the opposing surfaces of the bar members contact the board. The angle .beta. is between 102.degree. and 140.degree.. When the board spans a pair of supports, and a downward loading force is applied to the board, the edges of the bar members create indentations in the board which resist relative sliding movement between the board and the support.
