Microduct 16/12 mm

TWD 16/12 mm Primary Tube, ft

  • For direct burial
  • 16/12 mm microducts
  • Low friction inner surface
  • Longitudinal grooves for maximum installation lengths
Three thick walled microducts in green, orange and blue

The thick walled microduct are designed with an inner low friction surface that enables installation of micro cables or nano cables. The thick inner wall of the microducts allow for installation directly into the ground without the need for additional protection.

16/12 mm microducts are optimized for installation of micro cables and nano cables. The microducts have a low-friction inner surface with longitudinal grooves for best blowing performance.

Microducts: HDPE
