The Fremco Adaptor Plates (vendor part 103-130213005, Millennium part 513696) are sized for 11.0 x 14 mm duct and fit into a Fremco MiniFlow blower to match the machine to that duct diameter during jetting operations. Swapping in the correct plate size lets a placing crew run one blower across several duct sizes on a microduct build instead of stocking multiple machines. Cable placing crews keep a full set of plates on hand to stay ready for whatever duct size shows up on the job. Millennium carries the complete Fremco adaptor plate lineup along with MiniFlow blowers and Y-block assemblies.
