The CGW can be glued down to the roof, and the mat provides an extra protective barrier between the rubber base and roof surface. These C-Ports come with your choice of a TPO (Thermoplastic-polyolefin), PVC (Polyvinyl chloride) or EPDM (ethylene propylene diene monomer) membrane. The CGW is designed for support of gas and refrigeration piping systems, cable tray, electrical conduit, multiple lines, HVAC equipment and many other applications. C-Port Length 48", Mat lenght 54"
