ABSTRACT:
A framework for supporting a horizontal arm at one of a plurality of locations from a vertically extending member having a plurality of vertically separated openings, each of which can be aligned with a similar opening in one end of the arm. A pair of triangular section cotter pins extend through the aligned openings with the hypotenuses in contact and the other two dimensions being less than the corresponding opening dimension so that after pin insertion, downward movement of the arm, misaligning the opening, locks the arm to the member.
