Large Diameter Duct is manufactured from rugged
high tensile strength High Density Polyethylene (HDPE) to provide
complete protection and a permanent underground pathway for innerduct
and cable. Additionally, the natural flexibility of HDPE allows
the duct to bend with ground shifts and heaves... without breaking.
All of which helps prevent cable damage as well as facilitating
future cable placement and upgrades.

Large
Diameter Duct is designed and engineered for cost efficient placement
of main duct via direct bury or directional bore. 3" and 4"
Large Diameter Duct is available in continuous lengths on reusable
steel reels for fast, easy installation under highways, railways and
waterways... hostile environments in which placement of other types
of duct is extremely difficult and costly. 6" Large Diameter
Duct may be specified in "sticks" of up to 40' in length,
for those applications which require greater capacity duct.
