Ducting is the protective plastic channels which carry cables or pipes underground. They are colour-coded to a standard in order to quickly identify the utility they protect.

We stock 50m lengths of Ridgicoil ducting from Polypipe in black, blue, yellow and purple, in sizes 110mm and 63mm.

Ducts for underground cables follow a colour coding scheme so that the utility can be determined without removing the ducting. Below are a few examples of what these colours stand for.
