Drawing Head — The graduated protractor head locks at any desired angle with automatic settings in 15° increments. Constructed almost completely with plastic parts, it glides across the straightedge quickly and easily, except when the brake mechanism is used, making work like repetitive crosshatching and parallel line drawing quick and easy. Smoke colored.
