This professional-quality aluminum protractor takes the guesswork out of making angled cuts. It provides direct angle readings both for cutting mitered joints and for complementary angles in corner work.
You simply position the legs in the corner or on the workpiece and then read the appropriate dial scale for setting the miter saw to either bisect or complement the angle.
It also has a protractor scale for reading or laying out inside and outside angles (within a 180° range), a chart to make compound miter cuts for 45° and 38° / 52° crown molding, and a gauge for setting roof pitches from 2/12 to 16/12.
Accurate to about 1/2°, it has 12" legs that are 1/4" thick and 2 1/2" wide. Provides a quick solution to common problems in framing and trim work.
Made in USA.
