DEHN maadoitus-/seinäläpivienti 478450, 500-700 mm seinänpaksuus, 720 mm pituus, ruostumaton

Passing lightning protection conductors through walls or foundations while maintaining a watertight and gas-tight seal is a common challenge in building installations. The DEHN Earthing/Wall Feed-through 478450 solves this by providing a durable stainless steel conduit that accommodates wall thicknesses from 500 to 700 mm and offers a total length of 720 mm. Its M10 internal thread allows secure connection to round or flat conductors, ensuring reliable grounding continuity.

Who is it for

This feed-through is intended for electricians, lightning protection installers, and building contractors who need to route earthing conductors through walls, floors, or foundations in both indoor and outdoor environments. It is suitable for new construction and retrofit projects where a robust, corrosion-resistant passage is required.
