Ikelite 4081.3 1-inch Ball with Extended Sensor Mount for Quick Release Handle
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.
Cheaper old version #9571.3 (without o-ring)
