Dura-Line HDPE MicroDucts (12.7 mm OD / 10 mm ID) are small-diameter HDPE conduits that provide a pathway for fiber and microcables. Available in ribbed (ribbed-in) and smoothwall constructions, with optional SILICORE® ULF permanently lubricated lining and factory pre-installed pull tape, these microducts are supplied on 1,000 ft reels and offered in multiple colors (including Orange). They are intended for OSP and select indoor installations and meet applicable Telcordia/ASTM requirements for microduct products; plenum-rated variants are ETL/UL listed where specified.
