ABSTRACT:
A non-metallic pad for placement between equipment and its support, for example between a pipe and a beam supporting the pipe. The pad comprises an elongated main body, preferably having male and female dovetails on either end to permit connecting multiple pads together. In profile, the main body has a convex top and a flat bottom. The main body is of a lattice internal structure, with the ribs of the lattice running substantially vertically. The ribs terminate at one end against a closed top surface, and at the other end terminate at a common level to form an open bottom. Injection molding is preferably used to form the pad. Preferred non-metallic materials for the pad are plastics, including glass fiber filled polyurethane, glass fiber filled nylon, and rubber filled polypropylene.
