if you know any electricians they might have access to a larger crimper for something you need crimped or before you install the wiring take the cable and connectors to a shop and they would prob. do it for nothing.
idk....call around to some different electrical shops and see what they say.
You don't want to buy the tool for a couple of crimps unless you are going to do a sh*tload of crimps.
We crimp ground lugs on #6 ground wire all the time and you would need a crimp tool at least that big and that crimper is the same size as large bolt cutters.
