Recommended-clamps tight!

I was concerned when I bought this to match two products with 20 mm balls, but different companies. I didn’t need to be - this really clamped tight. I’m impressed.

Solid smaller mount extension

This is a small arm for smaller 1 inch RAM balls. It is a shorter extension at less than 3 inches. It works for its purpose. It is solid all metal construction with a metal lever. It has knobs inside the ends for gripping the RAM balls. Very high quality for such a petite package.
