Dual Ball Mount Socket ARM holder 20-22mm ball ends

This is a Dual Ball Mount Socket that holds 20-22mm ball ends made of aluminum alloy. Very strong and rigid. Will hold 20-22mm ball end adapters securely in place. The ball ends on this item are not included and must be ordered separately.  I do have them available on another listing if you want to order the set. This one here is sold individually without the ball ends.
