This is a high quality, precision, versatile and heavy duty steel protractor. It measures up to 170 degrees in both directions and the head can slide from one end to the other along a groove in the blade. The locking mechanism holds any angle and will not budge. It is made from hardened tool steel and finished with a "zero glare" satin chrome finish. The blade measures 12" (300 mm) in length, with a 8" (200 mm) wide protractor head. The blade is 0.140" thick and the head is 0.100" thick. Comes packaged in a protective vinyl sleeve for storage.
