Comes included with a soapstone crayon.
The Contour Standard Marker is a compact and timesaving tool that is used to lay out a pipe and structural steel joints. Laterals at any angle, tees, wyes, crosses, elbows - any type or size of a joint can be quickly and laid out precisely to how the operator wants. No more complications with mathematical formulas, no more trial and error, and no more material waste. The #1 Contour Marker consists of an X-shaped frame, rectified protractor, and a triple-jointed marketing arm and holder. The holder accepts a soapstone crayon, felt pen, or pencil. The frame can fold into a compact tool that can fit into a pocket or tool kit and can be used upside down or right side up. The protractor is calibrated on both sides - one in degrees and one in the rise-inches-per foot.
