Tronic PVC Junction Box 1 Way 20mm

Our review

This is a single-way PVC junction box from Tronic, sized for 20mm conduit entries. It is the kind of fitting electricians reach for when a run needs a protected joint or a simple branch point, and the PVC body is the main selling point: it resists corrosion, so it holds up in damp or dusty spots where a metal box would eventually suffer. It suits anyone wiring a home, shop or small workshop with 20mm conduit, and it is a sensible spare to keep in a tool bag. Before buying, confirm the conduit diameter you are using is 20mm, since a mismatch means the box will not seat properly, and check how many entries you need, because a one-way box handles a single run rather than several. Compare it with other PVC boxes of the same size on build quality and lid fit, and with metal alternatives if you need extra mechanical protection. Available on Sokonia.
