A bracket assembly for adjustably and releasably affixing bracket elements to an adjustable elongated support member includes a cylindrical base, at least one cylindrical core having an orthogonal arm, and a cylindrical cap. The bracket assembly provides adjustable vertical bracket positioning by the adjustable elongated support member. Abutting bracket assembly cylindrical cores provide a range of orthogonal arm positions 180 degrees or less, one to the other. The orthogonal arm provides additional 360 degree adjustable positioning for any element attached to the arm outward end.
