The DogBone Wire Brush encourages linemen to brush because it is uniquely designed to make wire brushing easier and more convenient than ever. The DogBone has two designated brushing surfaces, one side for copper and the other side for aluminum. The ends are color coordinated to allow lineman to keep one tool with dedicated brushing ends for two different surfaces. The round wire brush covers conductors up to 1590 MCM. This covers most conductors and both wire brushes are easily replaceable.
