PVC trunking is used to protect electrical cables and wiring which hasn't been installed within the wall. Keeping the cabling within a neat plastic routing also brings a clean and precise finish to an electrical installation. It can be used for new work and for upgrades, minimising damage to existing walls and ceilings. Plastic trunking comes in a variety of widths and sizes which can be adapted to any job. Slide and hinge opening allows for access after the work is complete for maintenance purposes.
