The Rule 150mm has incremental millimetre marks to both long edges allowing for the rule to be used to measure from the left or right. The back of the long edge of the rule has a bevel to minimise ink smudging. The rule also includes a 30mm end face with millimetre increments. The opposite end has two arcs that allow the rule to align with the edge circumference of either the Protractor 360 or Protractor 180. The two arcs allow the ruler to be positioned to either the left or right side of the preferred edge to be marked and aligns to the Protractor centre point allowing for accurate angled lines to be produced. The Rule also includes central dimensions that are from the two arcs end and allow for measurements from the edge or the protractor outwards. 152 x 30 x 3mm The Rule 300mm has incremental millimetre marks to both long edges allowing for the rule to be used to measure from the left or right.
