DEHN 478430 aardingsmuurdoorvoer, verstelbaar 300-500 mm, roestvrijstaal

Routing earthing conductors through walls often creates a weak point: moisture ingress, mechanical stress, and poor contact can compromise the lightning protection system. The DEHN 478430 wall lead-through solves this by providing a secure, adjustable passage for round and flat conductors through walls with thicknesses from 300 to 500 mm. Made of stainless steel (V2A), it resists corrosion and ensures a reliable connection in both indoor and outdoor environments.

Who is it for

This product is intended for electricians, lightning protection installers, and building contractors who need to route earthing conductors through masonry, concrete, or dry walls while maintaining system integrity and compliance with IEC 62561-1.
