Part 36255 is the clevis roller assembly for the GMP Tornado cable blowing machine. It installs in place of the microduct tube guide when a crew converts the Tornado from tube blowing to blowing fiber optic cable, letting one machine cover both duties. The roller supports and guides the cable into the drive chain without abrading the jacket. Contractors who alternate between installing microduct and jetting cable through it keep this assembly with the machine as a standard changeover part. Available from Millennium as part #526801.
