  • FRD 5/3.5 mm 1-24 -way HG

    • 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, antistatic 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. One unsheathed single duct version for minimal cross section is available for installation in existing external protective microducts or sheaths.
