Transition GRP Cable Trough

The Trenchlite® GRP Cable Trough system, innovated by Fibex provides a lightweight and cost-effective solution to pre-cast concrete troughs.


What does our GRP Trough range include?

  • Range of Straight, Tee, Right-Angle, 45° and Transition GRP Troughs
  • Custom bends available
  • Available in 300mm and 600mm depths as standard

Why choose Fibex’s GRP Troughs instead of precast concrete alternatives?

Fibex’s GRP Trenchlite® Trough/Trenches are capable of meeting D400 (40 tonnes) test load ratings with suitable Fibex GRP Trough Covers.

The reinforced design of Fibex’s GRP Cable Troughs/Cable Trenches offers a significant advantage over the typical polymer and composite concrete troughs. This is due to GRP Cable Troughs weighing around 90% lighter than pre-cast concrete.
