Ikelite 4081.72 1-inch Sliding Ball Mount Mark II
Mounts to Ball Arm Mark II Extensions for the addition of a lightweight accessory in the middle of your arm system. A three-pronged wing nut provides adjustability to slide your accessory up and down the length of the arm to reposition lighting easily during your dive. Requires a Ball Arm Mark II Extension, sold separately.
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.
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.
