  • For single-rolled TFS systems with a ventilation height of up to 3,5 m. 
  • Only a small winding tube offset (± 5 – 10 cm).
  • Only a small base is needed, which delivers a bigger cross section for ventilation with eaves at the same height.
  • Flexible range of applications: Depending on which area of the tapered drum is used, the winding offset for different thicknesses of sheeting can be optimised.
  • Easy to install with tried and tested gripper clamps.


  • Indication H without two safety windings.
