the size of leoben Underwater Camera Arms range from 2.3",3",3.5",4",5",6",8",10",12",14",16" all arms are decorated with an o-ring which greatly increases the friction forces at the joint. The o-ring also gets away from the metal to metal contact between the clamp and the ball of the arm. The lightweight pattern not only looks great; but also allows the arms to keep their required rigidity while keeping the weight to an absolute minimum.
