Using the Klein Tools 50400 cable bender is easy. First, place the cable in the 7/8 - inch tool opening. If you're dealing with a large cable, it's a good idea to use two benders for a smoother bend. The contoured handle gives you a great grip, so you can control the bending process comfortably. When you're done, wipe it down with a dry cloth to keep it clean. Store it in a dry place to prevent corrosion. And remember, this bender can handle cables up to 350 MCM, so don't try to bend cables that are too thick for it.
