Abstract
An attachment for a framer's square which permits the framer's square to be self supporting on a flat, horizontal surface. The attachment has an elongated support bar with two clips which may be inserted over a blade of a framer's square. This attachment, when inserted on the inner edge of the framer's square, facilitates the scribing of a right-angle line to a rounded edge and when placed on an outer edge, permits the square to be free standing.
