Add this trim to your single 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
