The ever-growing selection of lighting accessories on the market demands a mounting system that's highly expandable, flexible, and streamlined. In answer to this need, the second generation of our 1-inch ball arm system provides improved ergonomics and versatility in a lighter, sleeker package. Possible combinations are virtually endless, with opportunities to mount an additional lightweight accessory almost anywhere along the length of an arm.

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.

Works with 1-inch ball arms from Ikelite, TLC, Ultralight, Nauticam, and others.

Old and new Ikelite 1-inch balls and clamps are interchangeable. For the best performance, we recommend combining like components within a single clamp (two balls with grooves, or two balls without grooves). Ball components with an o-ring groove should have an o-ring installed at all times.

This ball mount replaces our Product Number 9571.31.
