Sales unit Meter Copy
ETIM-Class EC001474 Copy
  • Product specifications

    25/21mm microduct designed for long term protection of fiber optical cables and are especially suitable for installation of micro cables. Direct Bury type of microducts are thick wall products that attain their mechanical robustness and functional performance through their intrinsic thick walls and need no further protection in underground installations. The microduct are made of high-density virgin polyethylene (HDPE). Every microduct has a permanent, co-extruded silicone compound inner liner and longitudinal grooves giving a coefficient of friction of less than 0,1.
