The RAP-B-365-224-237U consists of a triple suction cup base, standard length double socket arm and 1" Ball with 1/4"-20 male threaded post. The triple suction cup base is designed to have an extra strong hold on any smooth, non-porous surface. For best results mount the suction cup on glass or non-porous plastic surface. The male thread matches most standard camera and camcorder female threads found on the bottom of the camera.
