Abstract: An adjustable support mount having a clamp plate with a fulcrum and a clamp plate extension. The clamp plate extension has a concave, circular toothed depression forming one half of a socket to hold a ball. The other half of the socket is formed by a jaw plate also having a concave, circular toothed depression positioned on the opposite side of the ball to the clamp plate extension. The jaw plate is positioned on the fulcrum and is kept aligned on the clamp plate by a keyway rib and slot structure. The jaw plate is tightened by a bolt or screw that passes through both the jaw plate and the clamp plate extension into a cap nut. The ball is attached to a shaft which is, in turn, attached to an ultimate support mount. Welded to and encircling the shaft is an eccentric ring. The eccentric ring and shaft are encapsulated by the ball, the ball material passing through and around the eccentric ring and shaft.
