The RAP-B-166-2U consists of a 2.75" suction cup twist lock base double socket arm and diamond base adapter. 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 allows for almost infinite adjustment and perfect viewing angles. The hole pattern found on the diamond base adapter will connect to most RAM cradles.
