NOT 6 inch clamp, suitable for power and hand tools.
Nothing on this clamp is 6 inches. The overall length is 8 inches, the width is 2 inches, and the maximum clip thickness is 2.5 inches. It is also not what is advertised as it is a very good 2 inch clamp.
Pros
Operation is as simple as turning a screw to adjust the compression and set the desired object.
