Jackson Safety #1 Marker standard 1 pc/box

This is a compact and timesaving tool that can be used to lay out pipe and structural steel joints.  Laterals at any angle, tees, wyes, crosses, elbows - any type or size of joint can be quickly and precisely laid out.  No more complicated mathematical formulas, no more cut and try, and no more needless material waste.  The #1 Contour Marker consists of an X-shaped frame, calibrated protractor, and a triple-jointed marketing arm and holder.  The holder accepts a soapstone crayon, felt pen, or pencil.  The frame folds into a compact tool that fits into a pocket or tool kit, and it can be used upside down or right side up.  The protractor is calibrated on both sides - one in degrees and one in rise-inches-per foot.
