Twin-wall flue duct KNd350H38/2 530335

Robust underfloor duct for running installations

This two-channel KNd350H38/2 duct, with a length of 2 running meters, is a reliable solution for safe and organized cable routing under the floor. Made of steel, with a hot-dip galvanized surface protection, it ensures durability and corrosion resistance – even in demanding conditions. A width of 350 mm allows for free laying of cables, and a height of 38 mm provides sufficient space for most standard installations.

Construction and application

This duct is primarily intended for running electrical and telecommunications installations in underfloor systems. Its solid construction of 1 mm thick sheet metal guarantees mechanical strength and resistance to loads. Steel galvanized by the Sendzimir method (PN-EN 10346:2015-09) is a proven material that provides long-term protection against corrosion. A version made of stainless steel (to order) is also available, which increases resistance to aggressive environments.

Advantages and benefits

• Durability and resistance: Hot-dip galvanizing and the possibility of making it from stainless steel ensure longevity and corrosion resistance.
• Capacity: A width of 350 mm allows for comfortable laying of many cables simultaneously.
• Mechanical strength: Sheet thickness of 1 mm guarantees resistance to mechanical damage and loads.
• Versatility: Ideal for running electrical and telecommunications installations in underfloor systems.
• Easy installation: Standard dimensions facilitate integration with existing underfloor systems.
• Compliance with standards: Made of galvanized steel in accordance with PN-EN 10346:2015-09.
