Contact Wheel Armm
Click pic for larger image.
This is my Contact wheel arm, Its 15" long and made of aluminum so therefore very light. In order to keep the threads strong I have inserted a 3/4" long helicoil so you will not strip out the threads when inserting the 1/2"-13 bolt to attach your contact wheel. Contact wheel arm and bolt ship for $120 in a tube via USPS. Link below if you would like one.
