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.

• Clamp with wingnut

• Accepts 1 in (25.4 mm) diameter ball
• Aluminum clamp plates and wing nut
• Type III hard coat anodizing

An 8” diameter dome made of optical grade acrylic. Comparable quality to glass yet significantly lighter and easier to handle, especially at the surface of the water. Not compatible with external filters.

This port features a longer base which is required with certain very large diameter zoom lenses. Refer to the DL System Port Chart for compatibility.
