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.
