The AC-TCSJK combines the ability to connect three 1" ball components with the increased articulation of Ultralight's single-cutout design. With up to 110° of side-to-side movement, it provides significantly greater positioning flexibility than the standard AC-TCS, making it especially useful for adding lights, strobes, action cameras and other accessories to custom underwater and cinema camera rigs.
