The RAM-B-166-GA26U consists of a 3.3" suction cup twist lock base, double socket arm and custom high strength composite cradle for Garmin nuvi devices. The suction cup base is designed to have a strong hold on glass and non-porous plastic surfaces, including RAM adhesive disks. 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.
