Starrett Metric Prosite Protractor, 7 in Aluminium Blade

The ProSite® Protractor takes error-prone calculations out of the process of miter cuts by simply setting your saw to the angle that you read.

The protractor uses two scales:

Red scale and arrow show the angle for a miter joint
Black scale and arrow provide the angle to fit a single workpiece to an angle

Upside down or backwards, the reading is always correct
Saves time and reduces waste
Ideal for carpenters, plumbers, and all building trades that require the measuring and transferring of angles
Also invaluable for home use
