67% lighter than the latest concrete C/1/8


33% more internal capacity than C/1/8

The TTS 200 Series is suitable for ground installation in ballast, on concrete plinths, wall mounted, or elevated on posts.


Its nearest UK concrete equivalent size is C/1/8. With a 33% greater internal capacity and a marginally smaller footprint to consider when excavating the ballast or earthworks, it offers the additional benefit of providing more space for future cable installations.


The TTS 200 series is also a troughing replacement for C/1/9 and C/1/10 with more internal capacity to carry extra cables. The series is ideal for using in confined spaces and mounting on walls.

The TTS 200 Series cable ducting system includes:

  • Straights
  • Bends
  • Gradients
  • Junctions
  • Accessories
