Twinwall Utility Duct Coupler - 137mm

Our twinwall utility duct couplers are used to connect two cut lengths of rigid ducting. Made from HDPE, the connection is a simple push fit joint.

All of 6m duct lengths and our flexible duct coils come with an integral coupler.

6 metres is the standard length for rigid ducting used underground, minimising the amount of joints that are needed.

Twinwall duct is made from HDPE (High Density Polyethylene), which is both strong and resistant to corrosion. Like our flexible duct, it is designed to meet the current compressive strength requirement of the Highways Agency.
