Jackson Safety 14783 Welding Jumbo Radius Marker

Product Description

The JACKSON SAFETY 14783 is a welding-grade jumbo radius marker designed to simplify pipe and structural steel layout work on the job site. This contour marking tool eliminates the need for complex math calculations or repeated cut-and-test cycles, saving time and reducing material waste. The tool includes a soapstone crayon and handles pipe diameters from 1.5 inches to 18 inches, as well as structural steel members up to 18 inches wide. It can be used right-side up or upside down, making it adaptable to a variety of positioning scenarios on the bench or in the field.

The 14783 is built for pipefitters, welders, and structural steel fabricators working in industrial, commercial, or heavy residential settings. It is well suited for laying out tees, wyes, crosses, elbows, and lateral branch connections at any angle. The X-shaped frame and calibrated angle protractor let the technician set precise angles quickly, while the triple-jointed marked arm and bracket maintain accuracy across a wide range of joint geometries. Any shop or field crew regularly cutting and fitting pipe or structural members will find this tool useful for repetitive layout tasks.

Installation Notes

This is a hand layout tool requiring no installation.
