One thing to keep in mind with kurt vises. If you tighten them more than 45 foot lbs. with a torque wrench the top of the solid jaw will start to tip backwards. Put an indicator on the backside of the solid jaw and try this. At 45 foot lbs it just starts to move. This will make squaring up stuff hard to do unless you know this. Good luck with your Kurt. They are hard to beat and last for years and years. Just don't pound on the handle like I see some people do.
