Ikelite 1" Sliding Ball Mount Mark II

Thanks to the slotted design of Ikelite's Ball Arm Mark II Extensions, their 1" Sliding Ball Mount Mark II can connect directly to the middle of the arm to allow for the addition and movement of a lightweight accessory, such as a focus light. A three-pronged wing nut lets you adjust the mount and slide your accessory up and down the length of the arm to re-position it easily during your dive.
