The RAM-B-102-237U consists of a double socket arm, diamond 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 diamond bases measure 2.43" x 1.31" diamond base and contain two holes 1.912" from center to center, positioned at both ends of the diamond base. 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.
