Review on Mount RAM B 138U Double Ball Surface by Aaron Ayo

I needed an extension to attach the RAP-299-2U RAM-A-CAN cup holder I bought, as well as a mounting ball. RAM-B-138U Double The flat surface ball mount was a perfect fit because it was the right length, the ball I needed and included a flat bonus plate. What's not to like? By the way. I've found that the ball has some sort of rubber or plastic coating and will deform under the pressure of the clamp, but the material "heals" if left unclamped for a while. I suspect this deformation provides a more secure fit once clamped. In general, buying components this way is very profitable (it would be more expensive to buy elements separately).
