The RAM-B-166-UN9U consists of a 3.3-inch diameter suction cup twist lock base double socket arm round base adapter and universal X-Grip clamping cradle for 10-inch tablets. The suction cup base is designed to have a strong hold on glass and non-porous plastic surfaces. The mount is designed with a RAM one-inch 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 clamping cradle consists of a composite spring-loaded cradle expandable grip arms and additional bottom support keeper. Included are extra-easy access grip knobs located on the back of the cradle for quick release of your tablet. The X-Grip clamping cradle expands and contracts for perfect fit of most 10-inch tablets with or without sleeves as well as some smaller tablets.
