DEHN passante di messa a terra/parete 100-300mm M10 acciaio inox 478410

Routing earthing conductors through walls often means compromising on sealing or corrosion resistance. The DEHN 478410 Earthing/Wall Lead-Through solves this with a telescopic stainless steel tube that adjusts from 100 to 300 mm wall thickness, providing a durable, corrosion-resistant passage for equipotential bonding and lightning protection systems.

Who is it for

Electricians and lightning protection installers who need a reliable through-wall connection for earthing conductors in residential, commercial, or industrial buildings. It suits both new installations and retrofits where wall depths vary.

Main features

• Telescopic design fits wall thicknesses from 100 mm to 300 mm
• Stainless steel (V2A / 1.4301) for high corrosion resistance
• M10 threaded connection for secure conductor attachment
• Accepts round conductors 8–10 mm and flat conductors up to 30 mm
• Compliant with EN 62561-1 for lightning protection components

Tips

For outdoor installations, ensure the lead-through is sealed at both ends with suitable compound to prevent moisture ingress. The telescopic tube can be cut to length if a shorter passage is needed, but maintain the minimum overlap for stability.
