Twin-wall flue duct KNd250H48/2 540325

Robust and functional BAKS underfloor channels

The KNd250H48/2 channel is a reliable solution for routing cable runs under the floor. Made of steel with a galvanized surface, it provides durability and corrosion resistance – particularly important in demanding installation conditions. Its two-way design allows for convenient and organized cable routing.

This 2-meter section of channel, 250 mm wide and 48 mm high, is characterized by a sheet thickness of 1 mm, which guarantees adequate stiffness and mechanical strength. Hot-dip galvanizing further protects against external factors.

Application and installation

These types of channels are widely used in commercial, office and residential construction. They allow for aesthetic and safe routing of electrical, telecommunications and other cable systems. Installation is simple and intuitive, and the solid construction ensures stability and long-term functionality.

Key features:

• Made of galvanized steel using the Sendzimir method (PN-EN 10346:2015-09) – a guarantee of high-quality material.
• Hot-dip galvanizing – increased resistance to corrosion and mechanical damage.
• Two-way design – allows for cable segregation and easy access.
• Sheet thickness of 1 mm – ensures adequate stiffness and strength of the channel.
• Length of 2 meters – facilitates adaptation to specific installation needs.
• Width of 250 mm and height of 48 mm – optimal dimensions for most standard installations.

Additionally, channels made of stainless steel are available to order, which provides an alternative for specific design or environmental requirements. The channel does not have properties to maintain operational efficiency during a fire (E30, E90 classes).
