The Fowler 52-440-777 Universal Dial Protractor, made of hardened stainless steel with a satin chrome finish, comes with 6" and 12" blades, an acute angle attachment, and fitted wooden case. The dial has a cutout window for degrees, with two colors and clock-style hand to facilitate reading, and has 12 divisions for each degree to measure intervals of 5 minutes. Blades are beveled 45° on one end and 60° on the other for fitting in tight spaces. The protractor has a positive locking lever. Applications include measuring angles in machines, metal molds, and jigs.

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.
