Beneath the Surface 1" Ball Mount Adapter with Anti-Rotation Pin

Connect your lighting arm system to your underwater photography or video tray system with the 1" Ball Mount Adapter from Beneath the Surface. The unit features a standard ball with a 1" diameter at one end, allowing for attachment to a ball-jointed lighting arm via clamps. The 1/4"-20 threaded bolt at the other end connects to an arm adapter or bridge bar on the tray system that holds your camera housing. Additionally, this version of the adapter is equipped with an anti-rotation pin to ensure that your ball mount remains fixed in place. The BMA is included with the single and dual strobe arm packages from Beneath the Surface, so this one here can serve as a spare or replacement part.
