Description
- Double-cutout 1" ball clamp provides up to 200° of side-to-side movement for maximum positioning flexibility in a compact clamp.
- Same compact 1½" center-to-center spacing as the standard AC-CSF, but with cutouts on both sides for substantially greater articulation.
- Ideal for positioning lights, strobes, monitors, arms and other accessories at angles that are difficult to achieve with a traditional clamp.
- Uses a 1/4"-20 coarse-thread 316 stainless-steel bolt and works with standard 1" ball components.
- Made from 6061-T6 aircraft-grade aluminum for strength and durability.
- Available with different knob colors to help identify or personalize your camera setup.
- Made in the USA and backed by Ultralight's lifetime warranty.
The AC-CSSK2 combines the compact size of Ultralight's standard AC-CSF clamp with double cutouts that provide up to 200° of side-to-side movement. The increased articulation makes it especially useful when lights, strobes, monitors and other accessories need to be positioned at angles that are difficult or impossible to achieve with a traditional clamp.
Single or Double Cutout?
- AC-CSSK — 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 — Double Cutout: Provides up to 200° of movement for maximum articulation and positioning flexibility.

I've been using ultralight products for about 30 years now. Even my oldest parts are still in use. I have absolute confidence in their lightness, holding power, and durability. This time, I purchased a clamp that isn't sold in Japan. I'll be using it for a long time to come.
