Mounts to DS50, DS51, DS125, DS160 or DS161 strobes for attachment to 1" (25mm) diameter ball arms from Ikelite, TLC, Ultralight, Nauticam, and others. Requires a compatible 1" Ball Clamp, sold separately.

The 1-inch Ball Arm System Mark II features 1" 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.

The replacement screw is sold as product # 0202.4.
