CURV-O-MARK Radius Marker Standard (J1886)

Models available in four sizes for scribing circles up to 80" in diameter 40" radius. All are a folding type design—the three smaller models will fit conveniently into a shirt pocket. All have sturdy friction joints to maintain rigidity and accuracy, and are made from lightweight, rustproof aluminum for long wear. A soapstone crayon is already installed in each radius marker. The scribe holder will accept round square or flat soapstone crayon, pencil, or steel point scribe.
