The updated UL Listings for Champion Fiberglass Duct® and Champion Fiberglass Haz Duct® conduits reflect extended support spacing distances, giving engineers another proof point when specifying Champion Fiberglass conduit. Underwriters Laboratory has conducted independent testing that validates the strength and rigidity of our extended support spacing distances, which are by now comparable to those of  GRC and PVC-coated steel. By utilizing Champion Fiberglass to meet the requirements of a rigid conduit system, users also enjoy the advantages of lower costs and superior performance.
