Draftex Scale Rules have been produced in accordance with Australian Standard AS 1212.
Colour coded centre sections to makes it easy to distinguish between the AS1212 - 2 (Blue) and the AS 1212-3 (Red).
They are manufactured of a tough ABS Plastic printed with 2 sets of graduations on each edge making 8 scales in all.
Available in 15cm pocket versions or 30cm for the desk.
The profile of the rule is described as being oval but this is really to state the difference between these and flat scale rules. Flat scale rules have virtually gone from the market as they were only printed on one side - the other being the flat underside.
Today we have the choice of oval or triangular.
Draftex Scale Rules are fantastic value compared with alternative brands.
