Sub-Duct

Our Sub-Duct range comprises smooth bore, solid wall polyethylene ducting manufactured to recognised industry dimensional standards. The system is available in a wide selection of outside diameters, colours, wall thicknesses and lengths to meet diverse installation requirements and is now ENATS 12-24 certified.

Designed to offer flexibility and resilience, the ducting performs effectively in variable ground conditions. Its lightweight construction allows it to accommodate trench irregularities with ease, while its high impact resistance significantly reduces the need for extensive bedding preparation or specialist surrounds in most installations.

Sub-Duct is supplied with plain ends as standard, with couplings available separately. The range can be provided in smooth wall, twinwall or single-wall corrugated profiles, depending on application requirements.
