Ducting

Professional Building Supplies stock coils of Black, Blue, Orange, Purple, Green and Yellow Duct. We also stock 54mm and 90mm BT Duct for cabling purposes and smooth electric polyduct to ENATS standards.

Although it is always wise to check with your Local Authority or Utility Supplier, ducting is generally colour coded as follows;

  • Black PVC-u (general purpose electric cabling)
  • Blue (water supply)
  • Yellow (gas) 
  • Orange (traffic signals)
  • Grey PVC-u (telecoms)
  • Red (high voltage electrical over 500V)
  • Green (cable television and telecoms)
  • Purple( motorway / road services)

All of our systems come with a variety of fittings and accessories, including standard Duct Access Chambers and the BT Quadbox chamber system.

Please contact us if you require further details. 

Further information about ducting can also be found in our Guides & Tips section.
