Fremco cable guide 103-140611002 is the 8 mm guide for MultiFlow fiber blowers, covering 5.5 mm to 7 mm fiber optic cable. It centers the cable on entry so it tracks straight into the chain set instead of wandering and scuffing the jacket. Correct guide sizing is what keeps small-diameter cable from buckling at the inlet, the usual cause of a stalled blow on drop and micro cable. A standard MultiFlow inlet component for FTTH crews. Stocked by Millennium as part #633288.
