20mm Flange Socket to 17mm Ball Adapter

This socket ball may be used to transform any of our fixed 20mm balls to a 17mm machined aluminum ball. Once converted, the 17mm ball can be used with third party arms designed for 17mm ball mounts. Like all of our 20mm ball mount products, this adapter provides almost infinite adjustability thanks to the integrated thumbscrew and includes the Bulletpoint Limited Lifetime Warranty.
