Compound Protractor - 6"

Compound Protractor - 6"

These protractors are the most versatile you've ever seen. They measure angles from 10 to 170 degrees, inside or out, with clearly legible scales and a locking pivot knob for precise marking & scribing. The small unit, in high visibility yellow plastic, has a short 3 - 1/2" long arm for use in tight quarters.
