Tronic Cavity Box PVC 1G, 29mm Deep

Our review

This is a single-gang cavity box from Tronic, made in PVC and 29mm deep. It is meant for fitting one electrical accessory into a cavity or hollow wall rather than solid masonry, so it suits anyone wiring partitions, stud walls or drywall where there is no brick or block to cut into. The 29mm depth keeps the box fairly shallow, which helps where the wall void is tight, but it also means you should check that your wiring and the accessory you plan to fit will sit comfortably behind the faceplate. Before buying, confirm the wall type and the accessory size match a single-gang cavity box, and compare with deeper boxes or metal back boxes if you need more room or a different fixing method. Available on Sokonia.
