A “roller-bearing” pipe support used to support roof-mounted gas pipes, electrical conduit, solar piping and other mechanical piping. Unique design absorbs thermal expansion and contraction of pipes thus preventing damage to the roof membrane. Pipes rest on a polycarbonate resin roller and a rod situated in a polycarbonate resin seat.
Each pipestand will accommodate up to 3-3/4″ outside diameter pipes.
