Description

Achieve structural perfection on every joint with the HARDEN 580723 300mm Steel Square. Designed for professional woodworkers, installers, and DIY enthusiasts, this L-square is the "workhorse" size for the shop—compact enough for bench-top cabinetry yet large enough for checking the squareness of shelving units, window frames, and structural brackets.

Forged from high-carbon hardened steel, the 580723 is engineered to resist bending and warping under pressure. It features permanently embossed graduations in both Metric and Imperial units, ensuring the scales remain legible even after years of sliding across abrasive materials like wood or metal.
