ACU-ARC Adjustable Ruler Centimeters
A ruler that eliminates the need for a beam compass or expensive curve sets. It can be adjusted to any radius, from 6 3/8" to 200" (17cm to 500cm), to determine the radius of an existing curve for dimension drawings, to find center lines and center points, or determine what a curve must be to fair in existing points, or lines, on a drawing. Still manufactured by hand, these rulers have been used by architects, engineers, chiropractors, designers, draftsmen, artists, woodworkers, metal workers, surveyors, carpet installers, and law enforcement for 45 years.
