This flexible gauge can measure inside or outside angles, lay out angles, check inside or outside corners for squareness, check surfaces for flatness, align saws by measuring cut angles and comparing them with machine settings, and lay out compound miters.
The continuous calibration lets you read angles whether the legs are crossed or spread. Made from tough, clear plastic that will not break, chip or warp in normal usage, it has an excellent adjustable friction lock that holds settings well.
It measures 11" long overall with legs closed. Overall accuracy is ± 1/2°.
Made in USA.
