A 180° protractor that has a 180mm circumference around the arc. The result is each degree mark is also a millimetre. The centre point is notched out for accuracy. Can be combined with either the Rule 300 or Rule 150 for easy angled line drawing.
Part of the Technical Collection for those seeking greater precision in their work. The tinted transparent grey acrylic allows you to see the working area. The markings are etched into the rear face making them easily legible whilst ensuring they can never be worn away over time. Made in the UK from Italian made 100% recycled and recyclable acrylic.
