Review on 📐 AdirPro Round Square Grade Leveling Tool by Chris Smotherman

Not sure if this would work on a 1.00-1.12 inch bar . It worked great. 2 spring metal arms and straighten and then gently grab the bar. I had to align it to mount the speakers on a stand. You seem to be able to calibrate this with 3 small screws, but I don't have anything to do that or compare. Maybe I'll try 2 levels on 2 sides of the bar and see if the bubble is in the middle.
