The Crucible Big Protractor is made for anyone who needs to set out angular measurements and requires something bigger (and more precise) than the plastic protractor from your school set. Suitable for woodworkers, joiners, carpenters, chairmakers and anyone else who makes things using angles that aren't 90°.  

The Crucible Big Protractor is almost 12” wide and made from 3.2mm three-ply acrylic laminate, which is laser engraved to give high-contrast markings. It is marked in single degrees for reading both clockwise and counter-clockwise.

The large scale of the Big Protractor, made in Ohio, allows you read (and mark) angles with greater accuracy. Marking and reading to a fraction of a degree is easy with the Big Protractor.
