IRWIN Vise-Grip 11R Locking C Clamp Regular Tip 275mm (11in), T19EL4

Does this clamp work with the kreg r3 jr. pocket hole jig?

Is this clamp the original Irwin or fake?

How deep can they go into the work? Not how wide do they open. From the overall lenght of 18" including the handle its less that that.

So what’s the difference in these now made in China and the harbor freight made in Taiwan clamps
