Double Plaster Trim
3mm 37342
In stock. Fast dispatch and delivery.
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
