MULTIduct™ is a multiple duct system, used for constructing under track or road crossings (UTX/URX), bridge crossings and linear routes.

Duct banks are built by connecting nominal 1 metre long sections, either by a steel clip or a push-fit system. There is also a range of accessories that offer flexibility in construction.

MULTIduct™ is manufactured from Nitrogen foamed-High Density Polyethylene, which offers high strength-to-weight properties, resulting in a product that has high crush resistance but can be lifted by a single person (all parts are below 25kg).
