M6 ball with a diameter of 2,5 cm, complete with a stainless steel screw. Anticorodal aluminum, anodized with 40 microns (military standard) to ensure maximum durability and excellent resistance to wear and to sea salt. It can be easily adapted to different supports, strobes, lights, and so on. An o-ring placed at the center of the ball is acts like a clutch: the ball tightened by the clamp can be loosened so as to move the arm in the water without having to re-tighten it.
