The RAM-B-166-A-237U consists of a 3.3" suction cup twist lock base, SHORT length double socket and 1" ball that contains a 1/4"-20 male camera thread. 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. The male thread matches most standard camera and camcorder female threads found on the bottom of the camera.
