Above ground conduit applications and standards

From conduit designed for high-impact areas to conduit that features the longer support span distances that create savings in under-bridge projects, Champion Fiberglass offers an overview of the specifications, benefits, and products that set Champion Fiberglass conduit apart in above ground applications.

Benefits of Champion Fiberglass RTRC vs. other in-market materials for above ground applications

Compare Champion Fiberglass conduit to other conduit materials, and you’ll find that the benefits speak for themselves.

Champion Fiberglass RTRC offers:

  • The lightest weight (for many diameters) of any in-market conduit product.
  • The lowest installation rates for most diameters according to the National Electrical Contractors Association (NECA) Manual of Labor Units.
  • Low burn through and ability to stand up to extreme conditions.
  • The broadest range of corrosion resistance of all in-market conduit products.
  • Shape retention after impact or compression.
  • Extended support spacing distances for several Champion Duct® and Champion Haz Duct® conduit diameters on par with those of GRC and PVC-coated steel. Champion Fiberglass is the only fiberglass manufacturer to offer UL Listed conduit featuring these expanded support spacing distances.
