- The AC-CSF clamp was the first to be designed using the standard knob you see today.
- It has 30 degrees of side-to-side movement and measures 1 1/2" between the centers of both ball mounting holes.
- It uses a 1/4"-20 coarse threaded stainless 316 bolt and works with any 1" ball.
- Knobs come in selected colors, black is Type III anodizing and color is Type II.
- Made out of 6061 T6 aircraft-grade aluminum.
- Will work in the harshest of environments, time-proven and built to last.
