Heavy Traffic H-20 Rated Retrofit “L” Channel

In-Ground Illustration Concast's "L" retrofit channel can be used in several different capacities:

  • Shore up damaged trench walls and protect them from further damage.
  • House and protect existing pedestrian trench from drive-over damage if you need to add a road crossing.
  • Installed retrofit channel around existing cabling; thus eliminating the need to excavate & move a cable system that needs additional protection.

Use reference drawing 88XX30HT_REF to guide you in choosing your covers and to calculate your trench spacing.
