The Ultralight AC-CSSK2-28 is a double cut-out ball clamp featuring a 1/4"-28 fine-thread knob for secure, precise adjustments. Designed for professional cinema gear and underwater camera systems, it works with standard 1" ball-mounted arms, strobes, lights, monitors and accessories.
The AC-CSSK2-28 takes the compact design of the AC-CSF-28 and adds dual cutouts for significantly greater positioning flexibility. With up to 200° of side-to-side movement, it allows lights, monitors, strobes and other accessories to be positioned at angles that can be difficult or impossible to achieve with a traditional clamp.
Single or Double Cutout?
- AC-CSSK-28 — Single Cutout: Provides up to 115° of movement and is a great choice when additional articulation is needed on one side of the clamp.
- AC-CSSK2-28 — Double Cutout: Provides up to 200° of movement for maximum articulation on both sides of the clamp.
