Hi,

I bought a bunch of Bessey K Body REVO clamps recently and decided to see if the fixed jaw was perpendicular to the bar. All of them were less than 90 degrees, somewhere between 1/3 and 2/3 of a degree off - 89:20 - 89:40. I took a look at my old (10+ y.o.) K Body clamps and they were similar.

Are these designed to first apply pressure at the end of the jaw and then, as you tighte the inner portion applies slightly less? Or is this a manufacturing flaw?

Thanks
