Mounts to the Auxiliary Ball Clamp for the attachment of additional lightweight accessories in the middle of your strobe arm. Requires the Auxiliary Ball Clamp, sold separately.

The 1-inch Ball Arm System Mark II features 1-inch ball components with a groove and o-ring to prevent slippage for improved holding power with less force. While underwater, clamps may be finger-tightened to keep lighting in place yet allow repositioning without loosening the clamp.

All parts are hard coat type III anodized for a long lasting, scratch resistant finish.
