Double Plaster Trim
3mm 37342
In Stock
€2,50
Add this trim to your double Corston back box so you can plaster it into the wall. It’s the best way to get a perfect finish and the switch or socket plate sitting exactly flush.
It raises the box 3mm away from the wall for skimming (use our 9mm trim for thicker rendering).
- Made from recycled and recyclable post-consumer plastic
- Fire retardant
