Starrett Protractor Head for Combination Squares, Combination Sets and Bevel Protractors – Reversible Head, Black Smooth Finish – PR-1224S

The Starrett PR-1224S Protractor Head, a reversible protractor head made of cast iron with a smooth black finish, attaches to combination squares, combination sets, and bevel protractors and fits Starrett blades 12″ and longer. It has revolving turrets with direct-reading double graduations, 0 to 180deg in opposite directions, for accurate reading of angles above or below the blade. The protractor head is reversible, with shoulders on both the front and back for reading on both sides. Protractors are tools that measure specific angles, which allow users to create and replicate desired angles. The tools include a stationary base and movable rule, usually connected by a scale that may be digital or manual. They are useful in a wide range of applications, such as measuring crown molding and installing baseboards. A protractor can be included as part of a combination set, along with a center and a square. A center accurately locates the center of a circle or cylindrical rod. A square is used to scribe right angles and parallel lines, calibrate miter and table saws, or as a miter, height gauge, or depth gauge. The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company, founded in 1880, is headquartered in Athol, MA.
