On the 15 ton one-shot bender, if you have it mounted flat on top of a table in the horizontal position, this is a handy addition to your tool box. Simply place the gauge over the tube while it is still in the bender and you will be able to quickly read exactly the degree of bend.
This is the most precise degree indicator Pro-Tools has ever seen. Built with aircraft quality, It has a magnetic base that grips like glue and it registers with perfect accuracy to within a fraction of a degree.
