The RAP-B-407-UN7U consists of the Tough-Wedge vehicle seat wedge base, composite double socket arm, and X-Grip universal phone 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 phone to the perfect viewing and operating angle. 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.
