The RAP-B-407-UN8U consists of the Tough-Wedge vehicle seat wedge base, composite double socket arm, and X-Grip universal small tablet holder. This mount fits conveniently in the gap between your vehicle passenger seat and center console, creating a temporary but also very rugged mounting platform for your phone. The mount is designed with a RAM 1" diameter patented rubber ball and socket system that has adjustment points at both ends of the double socket arm. With the turn of a knob you can set your most any 7"-8" tablet to the perfect viewing and operating angle. Included are extra easy access grip knobs, located on the back of the cradle for quick release of your tablet. The X-Grip is compatible with handheld devices that will fit the dimensions listed below. It is important to verify the dimensions of your handheld device with a case/sleeve/skin when determining the overall size.
