Sub Duct

Leading the Way in Low Friction

Radius offers a comprehensive range of HDPE and LSZH sub-ducts for the protection and management of cables in underground networks in open cut, trenchless and indoor applications.

Choose from our Direct Bury, Direct Install, Moleploughing & HDD and Fire Retardant series with diameters ranging from 18mm to 63mm.

Radius sub-ducts are designed for cable blowing & pulling and are made from HDPE (High-Density Polyethylene) offering class-leading performance thanks to our proprietary permanent co-extruded low friction HDPE inner lining for optimised cable installations.

Our Sub ducts are available with ribbed or smooth inner bore according to your preference and can be supplied pre-roped or pre-cabled on single or multi-way drums.

In addition, we offer a comprehensive range of fittings and accessories including bends, connectors, spacers, seals and access chambers.
