Fremco part 103-200210253 is the adaptor and duct clamp set for 16 mm duct on MultiFlow fiber blowers, priced per each. The set adapts the machine inlet to 16 mm microduct and clamps it firmly so the duct cannot retract or leak under working air pressure. Because the adaptor and clamp are matched, a single order covers the full inlet interface for that duct size rather than mixing loose components. A core changeover item for crews blowing fiber optic cable through 16 mm microduct. Millennium part #586910.
