Not really degree of bend (DOB), but this gauge set will tell you the inside or outside radius of a bent tube or sheet metal panel from 6-144 inches. Typically used for roll bending or slip roll applications, there is also a small radius set for rotary draw style bending. See those here. For Degree of Bend you would want to use an Angle Finder or Bend Protractor.

If you look at the additional photos, you will see that it fits onto the Inside or Outside Arc Master to help you see how the tool fits up to the bend rather than just three individual points. It flexes as you adjust the tool but doesn't actually help measure a variable arc.

“Haven't gotten to use them to much yet but they will be very helpful in the future, perfect for handrail work. Only wish there was one for even larger radii, occasionally do 200' dia or bigger, I know that a huge step up from 12' but anything larger would be helpful”

Just want to say this bender is awesome. I was concerned at first about the extra money for air/hydraulic conversion, but it was well worth it!! The service from ya'll was great - never had anyone (businesses) call and make sure I was happy with the shipping and get so many parts shipped so quickly!! Thanks Again.
