What's special about riser tubing?

  • Nonmetallic flexible raceway or conduit is used to manage and protect cables in riser applications, so that installations meet or exceed building codes
  • Pull tape can be pre-installed on 1" through 2" diameters to facilitate the threading of cables through the conduit
  • Approved for direct burial applications, to protect your underground cables from degrading in moist environments

Carlon Riser-Gard Conduit is designed to meet building code NEC 770/800, which works to prevent the spread of hazardous gases or fire between floors of a multi-story building or unit. This corrugated tubing is not only rated to meet building codes but also provides a safe and organized environment for your valuable telecommunications and fiber optic cables.

Questions & Answers


I need 2" conduit 125' long. Do you sell a coupler that can attaché additional 25' to the 100' length that you sell? Can I purchase this 2" conduit in longer than 100' lengths?

Asked by Anonymous user on 01/3/2017 6:13 PM

  • - Thank you for your inquiry. Unfortunately we do not offer a 2" coupler. The largest size we carry is 1 1/4".

Riser-Gard® Corrugated Conduit: can it be split to fit over existing cables?

Asked by Anonymous user on 11/20/2017 11:11 PM

  • - Although it does not come split, it can be split manually as long as the conduit is bigger than the existing cables.
