Riser-Gard® Corrugated Conduit

Rugged, Lightweight and Perfect for Riser Applications


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.

    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 06.13 PM Tuesday, 03 January, 2017

    • - 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 11.11 PM Monday, 20 November, 2017

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