This is a RAM ball joint motorcycle mount phone holder, designed to fit a Pixel 2XL in a rugged case. The inner diameter of the ball joint is 0.5mm smaller than the ball itself to ensure a tight fit that won't move around. In addition, there is a 3mm hole in each side if you want to add some screws for extra support. The mobile holder and ball joint adapter both fit the standardized 30x38mm mounting pattern for RAM adapters.
