RAPID RULE ADJUSTABLE TRIANGULAR SCALES

$18.50

Designed for the exacting needs of architects and engineers, these metal rules are ideal for reading reports, graphs and printouts. Treasured tools for anyone who works with drawings or prints, especially those involved with architecture, building projects, engineering or construction.
The patented scale rod allows all six scales to read off the same edge, unlike the six edges on a traditional triangular scale that has to constantly be flipped to gain access to a different scale. Turn either end knob to view one scale at a time. All scales read from left to right. And, most importantly, the selected scale is retained until purposely changed. It's always ready to use.
The edges of the Rapid Rule are raised to reduce ink smearing for clean, crisp lines. They are accurate to 0.006" and are checked during manufacture against international standards. The Rapid Rule is made in the U.S.A. of solid extruded aluminum. It is built to easily outlast normal plastic rules, and is much more resistant to nicking of the edges.
Available with Architect (6" and 12") or Engineer (12" only) graduations.
