Casing n Caping
uPVC surface trunking with a snap-on cap — for exposed wiring runs, rewiring in finished buildings, and anywhere chasing walls isn't an option.
Product overview
Surface wiring, finished neatly
The casing is fixed to the wall, cables are laid in, and the caping snaps over the top. No chiselling, no replastering, no repainting the whole room — which is why it's the standard answer for rewiring an occupied house, a shop fit-out or a rented premises.
- Snap-fit cap holds firm but lifts off cleanly for later access
- Rigid uPVC — self-extinguishing and non-corrosive
- Takes paint, so it can be finished to match the wall
- Cuts with a hacksaw on site, no special tools
