Three-roller Model 91605 accommodates copper cable bundles up to 4 in. dia; Model 91606 handles bundles to 2 3/4 in. dia. Cable guide is manually propelled by integral tow hook, as front and rear strand wheels ride on support strand diameters from 1/4-7/16 in. This eliminates need for hitch weldment to attach to lashing machine. Bearing-driven aluminum rollers minimize friction when handling heavy cable.
