Abstract: A support base is disclosed for distributing a concentrated load over a generally planar surface. The support base comprises a baseplate formed of a moldable polymeric material having a top surface and a generally planar bottom surface. A tubular sleeve is formed integral with the baseplate and extends from the top surface defining an upper portion and a lower cavity portion. A cap, also formed integral with the baseplate, is oriented at the distal end of the sleeve lower cavity portion, thus defining the cavity height. A through bore is formed through the cap generally coaxial with the cavity. An array of projections, formed integral with the baseplate, extend upward from a top surface of the cap and are spaced around the through bore such that the distal ends of the projections provide a generally planar upper mounting surface.
