Kaufhof APM-1277 is a versatile tool that allows the angle and depth to be measured simultaneously. The rule is graduated in both imperial and metric dimensions up to 150mm / 6in and a knurled thumbnut allows the rule to be locked at the chosen angle. The protractor features deep etched graduations 0 - 180° in opposite directions permitting the reading of both the direct and supplement angles.
