Flexi Underground Ducting Electric - 40mm (O.D.) x 50mtr Black Coil

Our black underground ducting is used for ducting all kinds of electrical installations with a voltage rating up to 500 volts. It is available in a range of coil diameters from 40mm up to 110mm. These measurements refer to the outside diameters (O.D.), all dimensions can be found in the table alongside the product image.

The ribbed external wall ensures that the duct can withstand high compressive forces whilst the smooth inner bore resists any snagging.

You should choose a diameter that allows plenty of room within the duct to allow the cable or cables to be drawn through smoothly.

All full coils come with an integral coupler and a pre-installed draw cord. The coupler enables two coils to be connected together as required.

The length of this coil is 50m.

Flexible ducting has two main advantages over rigid duct lengths. As flexi duct is available in relatively long lengths (the standard coil length is 50m), this minimises or eliminates the need for joiners, with duct often being cut to the exact size required.

The main advantage of flexible ducting though is the innate manoeuvrability flexibility of the product. This enables any small obstacles to be avoided or required changes of direction to be achieved without the need for additional fittings, saving cost and time.

If you are using flexible duct on your own property, we would always recommend attaching a second drawcord to your cable or pipe when you first install the service. This will enable you to easily install additional services at any point in the future if required.
