The Steel City Granite Angle Gauge provides a higher level of continuous accuracy. Utilizing solid Black Granite, the densest of all forms of granite, this angle gauge will not swell or shrink – regardless of shop conditions, it remains stable and accurate. Ideal for checking 90 and 45 degree angles, this unit has a perpendicular accuracy of .001" and a tolerance of +/- 0.1 degree of accuracy over the length of the angled plane. Includes a case for convenient storage.
