ACU-ARC Adjustable Flexible Curves

ACU-ARC adjustable curves are made of incredibly flexible, shape-holding butyrate plastic that can be finger-shaped to any curve for extremely accurate drawings and layout. One edge is flat-to-surface for pencil, and the other side has a bead for ruling pen. Available in several convenient sizes.

Adjustable curves are perfect for quilters, designers, draftsmen, artists, and more. Still manufactured by hand, ACU-ARC rulers and curves have been used by architects, engineers, chiropractors, designers, draftsmen, artists, woodworkers, metalworkers, surveyors, carpet installers, and law enforcement for over 45 years.
