The extensive underfloor range includes CHALI duct systems. These screed-flush brush ducts are optimally suited to the requirements of modern building equipment in offices and public buildings. They allow cables to be routed horizontally across the room or directly on walls and feature coverable brushes and removable covers. The ducts consist of a pre-assembled, height-adjustable upper and lower part. They allow VDE-certified applications in which electrical installations can be supplied with power at any point along the duct. This means that nothing stands in the way of flexible room design in spaces with dry-cleaned and wet-cleaned floors.
