pipestand, to 3 7/8" od pipe

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. 3" ID maximum pipe capacity. 3-3/4" OD maximum pipe capacity. Pipe clearance is 2-1/8", even load required. Manufacturer's recommended spacing is not to exceed 10 feet centers depending upon the load. Make certain each pipestand is properly elevated to even load weight at all pipestands.
