Fremco cable guide 103-10453 is the 12 mm guide for MultiFlow and Power fiber blowers, covering 7 mm to 11 mm fiber optic cable and priced per each. It aligns the cable into the chain drive so feed stays straight and the jacket clears the housing without abrasion. The 7-11 mm window takes in much of the distribution cable used on middle-mile and MDU work, making this one of the more commonly stocked guides. Order alongside the matching cable gasket for the same diameter. Millennium part #586900.
