coilable, and can be pulled into existing conduit in a manner similar to that of conventional innerduct. Placement Innerducts are primarily installed in underground conduit systems that provide connecting paths between manhole locations. In addition to placement in conduit, innerduct can be directly buried, or aerially installed by lashing the innerduct to a steel suspension strand. As stated in GR-356, cable is typically placed into innerduct in one of three ways. It may be Pre-installed by the innerduct manufacturer during the extrusion process, Pulled into the innerduct using a mechanically assisted pull line, or Blown into the innerduct using a high air volume cable blowing apparatus.
