This adapter fits snugly into the driver's side dashboard cubby and includes a 1 inch (B size) ball mount which allows attachment of a variety of devices from smartphones to tablets. Your mounted device can be positioned away from the windshield or air-vents for improved safety and comfort. Made with polycarbonate, one of the strongest and most durable plastics, and will not deform in high temperatures. An imbedded nut secures ball mount to adapter preventing rotation of the mount. Compatible with VS30 Mercedes-Benz Sprinter (2019 and later) and Winnebago Revel (2020 and later) vans.
