The RAM-B-101-C-UN9U consists of 2.5" diameter round bases with the universal amps hole pattern, long double socket arm and universal X-Grip III clamping cradle for 10" tablets. 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; this allowing for almost infinite adjustment and perfect viewing angles.

The X-Grip III clamping cradle expands and contracts for perfect fit of most 10" tablets with or without sleeves, as well as some smaller tablets.
