If buying replacement cable, be sure to get the same size cable for the adapter. For example, a 3/8" adapter won't work with a 5/16" cable. To switch from one size cable to another, buy an extra drum. It’s easier to change a drum with the cable already in it than to take the cable out of a drum and reload it.
The C-4, C-6, ,C-8, C-31 and C-32 cables use the T-200 series of tools. C-44 cable uses the T-100 series of tools.
Note that for use on roots, there are several cutters; they must be used with heavier C-44 cable.
