Twelve Metric Scales on One 30cm Triangular Rule

The Helix 2212093 Triangular Scale Rule 30cm, which ACCO lists with the Helix reference K93X40 (K93X70), carries 12 scales for reading and drawing plans at full size and at reduced sizes.

ACCO lists the scales as 1:1, 1:10, 1:2, 1:20, 1:5, 1:50, 1:100, 1:200, 1:500, 1:1000, 1:1250 and 1:2500, and names architects, engineers and designers as the users it is made for. The product photo shows a white body with a red band and the word METRIC printed beside the Helix name.

With the scales spread around the rule, one tool covers site plans, floor plans and detail drawings without hunting for a second ruler on the desk. ACCO notes that the triangular shape gives stability, which helps keep the chosen edge steady on the sheet while you read off a measurement.
