Starrett C359FZ Precision Universal Bevel Vernier Protractor, Through 360 Degree Graduations, 7" And 12" Blade Size

The dial of the protractor is graduated both to the right and left of zero up to 90 degrees. The vernier scale is also graduated to the right and left of zero up to 60 minutes (60'), each of the 12 vernier graduations representing 5 minutes. Any angle can be measured, and remember that the vernier reading must be read in the same direction from zero as the protractor, either left or right.

• Satin chrome finish on all reading surfaces
• Machine-divided graduations read to 5 minutes (1/12 of a degree) and accuracy is finer than can be read
• Blades can be rotated and length adjusted, as required
• Dial and blade can be locked independently
• The most convenient, ultra-sensitive fine adjustment for precision setting
