The Draftex PT360 and PT180 protractors are manufactured by ATI in high quality plastic. The graduations are printed traditionally around the outer circumference and then in the reverse direction on the inner. The crossbar is located off centre allowing the actual centre point to be marked exactly where it lies. This means it is possible to mark your own centre before drawing or measuring the required arc.
