The Fremco Blowing Tip, 3.0 mm to 4 mm (K03S, Millennium part 534367) seals the blower head around small-diameter microduct, focusing air pressure behind the cable as it jets through drop or distribution microduct runs. Packed five to a set, it's sized for the smallest duct diameters common on FTTH drop installations. As a wear part, crews keep spares on hand for continuous placing work. Millennium stocks the complete Fremco blowing tip lineup up through larger diameters for other duct sizes on the same blower platform.
