Fowler 52-440-612 Stainless Steel Bevel Protractor with Magnifier ...

The Fowler 52-440-612 Bevel Protractor comes with 6" and 12" blades and has a magnifier lens for easy reading of vernier scale and dial. The dial is graduated over 360° in 0 to 90° sectors, rotates around the full circle, and provides readings to 5 minutes of arc on the vernier scale. The blade has beveled ends (one 45° and one 60°) for fitting in tight spaces, slides the full length, and is fastened by a knurled thumb lock. The fine adjustment knob enables precise measuring. The base, blades, and angle attachment are made of hardened stainless steel. The protractor has a satin chrome finish for reading ease and comes with a fitted case and with an angle attachment for measuring acute angles.

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 Fred V. Fowler Company manufactures inspection and measurement instruments such as electronic indicators, calipers, bore gages, and digital scales. The company, founded in 1946, is headquartered in Newton, MA.
