Abstract
Abstract A clamp comprises a U-shaped rod with a semicircular bight portion that embraces a rear side of a post. Its legs project forwardly from the bight portion, to overlie the top edge of an edgewise upright board, thence downwardly to confine the board against the post. The bight portion can be welded to a length of tubing that encircles the post and through which a set screw extends. Or a second member having a semicircular post embracing portion can be rigidly connected to said bight portion by an elongated element that holds the semicircular portions coaxial, spaced vertically and opening forwardly.
