CHALI underfloor duct systems are screed-flush ducts with coverable brushes and removable covers. They are composed of pre-assembled, height-adjustable lower and upper parts including assembly covers and are suitable for dry-cleaned and wet-cleaned floor coverings in rooms with office traffic loads. The ducts are made of sendzimir hot-dip galvanised sheet steel (DIN EN 10346) and come in sections 2000 mm long and 255 mm wide. They can be used with floor coverings up to 25 mm thick and are installed at a minimum installation height of 92 mm. Their levelling range can be adjusted with the help of levelling bases. (UBDSLF 80: 92-160 mm; UBDSLF 150: 158-230 mm; UBDSLF 220: 228-300 mm). With the use of the UGM-SLF impact sound sleeve, the levelling range is increased by 3 mm. The barrier-free system can be laid directly along the wall, at window fronts and without a trip hazard in the middle of the room.
