FRE Composites manufactures a complete line of Below Ground Fiberglass Conduit products designed for either Direct Burial (DB) or Encased Burial (EB) applications as described in the National Electrical Code (NEC) and Canadian Electrical Code (CEC). UL Listed and CSA Certified, FRE® Below Ground Conduit system products are used the world over by power and telecommunications utilities as well as commercial and industrial markets. Using our TriSeal™ eliminates the need for adhesive, saving time and cost on field assembly. Our conduit contains no chlorine, halogen or other toxic materials and has a temperature range from -40 ºF to 230 ºF (-40 ºC to 110 ºC). High temperature rating results in no cable fusion. Also providing a low coefficient of friction, smooth inner wall results in longer cable pulls without burn through and fewer manholes. Impervious to a wide spectrum of chemicals and fuels.
