A generally disc shaped, unitary body is configured with a flat top surface for mating against a tripod head. An upper side annular surface defines a fanned array of threaded bores on radial axes for receiving and supporting extension rods leading to suction cup fasteners. A lower side surface of frusto-conical contour, converging downwardly, depends from the upper side surface and defines a fanned array of threaded bores on axes angled outwardly and downwardly. A bottom face at the lower end of the lower side surface is a planar ring that defines vertical bores distributed around the ring. A central cavity wall is configured as an upwardly tapering conic frustum, connected at its lower end to an inside edge of the bottom wall. The cavity wall defines a fanned array of threaded bores on axes angled inwardly and downwardly. The top of the cavity wall defines a countersink suited to receive the head of a tripod head mounting fastener. A center bore extends from the countersink to the top surface for receiving the tripod head mounting fastener and securing a tripod head to the top surface. The central cavity wall also defines two through bores to the top surface, carrying compression screws for stabilizing engagement with a tripod head. The bores for the compression screws and the center bore are arranged in a triangle. Extension rods and suction cup fasteners can be oriented as required to secure the tripod head to sharply angled external surfaces.
