New: BIS Aero® for spiral ducts
The BIS Aero® is the first clamp in the world where the rubber lining is securely attached. Unlike other clamps, the rubber lining on the BIS Aero® is conjoined with the steel and won’t come off when sliding the spiral duct through the clamp.
Patented quick locking system
The newly designed and patented quick locking system from the BIS Aero® enables safe and easy fixing of spiral ducts. The range covers all common spiral duct sizes from 80 up to and including 1.250 mm. The BIS Aero® is made of steel, pre-galvanized and the noise insulating lining is made of TPE rubber.
