Don't waste your time or money with this piece. I have an old version of this piece and it was great. I needed another so I bought this newer version. It looks like it was made by a 5th grader on a bench grinder. When I installed it I tightened it slowly with an Allen wrench, try to rotate it on the battery terminal with just my hand and it turned, tighten a little more, twist and tighten a little more, and it broke. Total rubbish.
