RS PRO Through Box, Conduit Fitting, 20mm Nominal Size, Steel

Need to protect your cables while routing them together in a single direction? Choose this RS PRO through-box cable conduit fitting. It provides a secure closure thanks to its two M4 tapped (50·8 mm centre) holes for fixing the lid. There's also an M4 tapped hole in the base for an earth screw that increases safety by allowing you to ground your circuits.


The through-box has a corrosion-resistant galvanised steel construction that can withstand heavy-duty applications. This means it helps protect your cables from damage even if you're running them underground or through walls.


As part of the RS PRO range, this component has been stringently tested for quality and reliability. You'll find through-box fittings like this one in domestic power grids, as well as in industrial and commercial electrical systems.
