Ikelite 1-inch Ball Clamp Mark II for Lightweight Accessories - 408121

Ikelite Product Number 4081.21

The Accessory Clamp attaches two (2) 1-inch diameter balls. In travel, every ounce counts so we reduced plate thickness and chose a light, three prong wing nut to reduce weight as compared to our Standard Clamp. The result is a lighter, maneuverable clamp with the perfect amount of holding power for small lights and accessories which weigh less than one pound. Plates are spring-loaded for easy assembly and breakdown of your arm system.

About Our Ball Arm System Mark II

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.
