The RAM-B-166-A-GOP1U consists of a 3.3" diameter suction cup twist lock base, SHORT length double socket arm and 1" diameter ball with custom GoPro® Hero adapter. 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 suction cup, twist lock base is designed to have a strong hold on glass and non-porous plastic surfaces, including adhesive disks. The GoPro® Hero adapter attaches directly to the under-side of the camera, replacing the factory mounting bracket. It is made of high strength composite and powder-coated, marine-grade aluminum for durability and reliability in the most demanding environments. It utilizes B size RAM components and has a 2 lb weight capacity. The suction size is 3.3" in diameter and the plate size is 2.5" in diameter.
