Versatile, precise and convenient, the Wixey™ Digital Protractor measures angles in any plane with 0.1° resolution, accuracy, and repeatability. At only 3", it is small enough to work in a tight spot. Use it for a variety of applications, from measuring and layout to setting miter and bevel angles. And with magnets on every blade edge, it’s especially easy to use on metal. It also features a convenient tightening mechanism for holding measurements.
