Abstract: A support base for distributing a concentrated load over a contact surface is disclosed. The support base includes a body formed of moldable polymeric material having a top surface and a generally planar bottom surface. At least one recess is integrally formed in the top surface for receiving a support member. The support member transfers the concentrated load to the planar body. Furthermore, at least one through bore is provided in the support base, and the through bore extends from the top surface to the bottom surface of the support base for receiving a fastener. The through bore has a shaft portion and a relatively oversized cavity portion adjacent to the bottom surface for receiving fasteners such as nuts for securing bolts, as well as, bolt heads of different sizes and configurations. The support base has many advantages over the prior art for example, the base may be attached to different interface bracketry without be modified.
