FRD 5/3.5 mm 1-24 -way HG OFNR

  • For indoor installation
  • 5/3.5 mm microducts
  • Halogen-free, flame-retardant, high grade
  • 1, 4, 7, 12, 19 or 24 over-sheathed ducts
  • Low friction inner surface for maximum installation lengths


        The indoor tight protected duct assemblies consist of a number of microducts with an inner low friction surface that enables installation of air-blown fibers. These microducts are highly flame retardant and therefore suitable for indoor use.


        The duct assemblies are available in several versions from 1 to 24 microducts . Each microduct has an outer/inner diameter of 5/3.5 mm. The microducts and duct assemblies including the outer sheath are made of halogen-free, flame-retardant polymer.

        The flame retardant properties are verified according to UL1666 OFNR Riser, as well as all relevant IEC standards.
