The RAM-B-101-A-237U consists of a short double socket arm, 2.5" diameter round base and 1" diameter rubber ball, connected to a 1/4"-20 camera thread. The male thread matches most standard camera and camcorder female threads found on the bottom of the camera. The round base contains pre-drilled holes, including the universal AMPs hole pattern. Designed into the mount is a 1" diameter patented rubber ball and socket system with adjustment points at both ends of the socket arm; this with a twist of the arm knob, allows for infinite articulation and optimum viewing angles.
