DESCRIPTION
The Planet steel squares are perfect for both general workshop tasks and engineering projects. They're crafted to accurately find 90 - degree angles, meeting the BS939 standard. The 3 - foot model is designated as ES3.
To use these Planet steel squares, simply place them against the surfaces where you need to measure a 90 - degree angle. They work well on various materials in your workshop or engineering site. When handling, be careful not to drop them as it may affect their accuracy. After use, wipe them clean with a dry cloth to prevent rust. Store them in a dry place away from moisture to keep them in good condition for a long time.
