The Fremco Chain Support Rail, PowerFlow (103-10094, Millennium part 41954) guides the drive chain through Fremco PowerFlow cable placing machines during a pull, keeping the chain tracking straight so it doesn't jump or bind as it feeds cable into duct. It's a wear part sized specifically for the PowerFlow platform, replacing worn rails without a full machine teardown. Cable placing crews keep spares on hand since the rail sees continuous contact during every run. Millennium also stocks the Multi/DuctRod rail variant for Fremco's other chain-drive placing units.
