Jackson Safety Contour Radius Marker – Aluminum, 24-Inch Radius, Standard Size

Overview

The Jackson Safety Contour Radius Marker in Standard size blends portability with precision for layout work on wood, metal, and other materials. Its folding design lets you slide it into a shirt pocket or clip it to a tool belt, keeping your marking tool within reach. When you’re ready to mark, the tool scribes circles up to 48 inches across, equivalent to a 24 inch radius, helping you establish consistent reference points without repeated measuring.

Made from lightweight aluminum, it resists rust and remains sturdy through daily job site use. A robust friction joint system helps maintain rigidity so your circle lines stay true as you work. A soapstone crayon is already installed, and the marker holder accepts round, square or flat soapstone crayons, pencils, or steel point scribes sold separately.
