This is the Rotational 3-Jaw Clamp #R-CJR-3.

The 3-jaw clamp is used to hold cylindrical parts, allowing the probe to measure or scan around the part without any interference. It can be mounted to a base plate in a vertical or horizontal position. The jaw design allows parts to be clamped from outside or inside the diameter, depending on requirements and rotated to a marked increment. It accommodates parts of Ø1 mm to Ø62 mm and is recommended for use on CMMs, the Equator™ gauging system, and vision and multi-sensor machines.

This is a universal component suitable for thread sizes M4, M6 and ¼-20.

Note: Included: socket head cap screws and chuck keys.
