The RAM Stubby cup holder base is a low-profile alternative of RAM's cup holder mounting base, and is a nice alternative to windscreen-mounted suction cup mounts. The durable composite shell construction and flexible support fins can be trimmed to size make this cup holder base a portable and versatile solution. The mount is designed with a patented RAM 1" diameter rubber ball. The RAM ball and socket system allows for articulation at both ends of the double socket arm creating almost infinite adjustment and perfect viewing angles. 

Compatible with any vehicle cup holder with an inside diameter range of 2.57" to 3.5".
