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