This metalworking miter square is built for welders, pipe fitters, and metal fabricators who need reliable angle layout on real shop materials. The long hypotenuse flange design solves a common problem: standard squares rock or slip on round tubing and irregular stock. By referencing off the flat sides of the workpiece instead, this tool gives you a clean, stable edge for marking 45°, 90°, and 22.5° cuts accurately the first time.
The thick-gauge metal body holds up in active fabrication environments. It resists heat, weld spatter, and the kind of daily handling that shortens the life of lighter tools. Laser-engraved markings stay readable through repeated use and don't fade the way painted or printed scales do.
It works on square tubing, round pipe, angle iron, and flat steel - the materials most commonly used in structural welding, pipe layout, and general metal fabrication. Available in 5", 8", and 10" sizes to match the scale of your project, from handheld fitting work to larger frame assembly.
A straightforward, well-made welding layout tool that fits naturally into a standard metalworking setup. No complicated setup, no extra accessories required.
