Granite Square Ruler
The granite square—also referred to as a granite reference square or rock square—is a high-precision geometric metrology instrument fabricated from naturally occurring, dimensionally stable granite. It serves as a primary reference standard for verifying perpendicularity, parallelism, and flatness of mechanical components and assemblies, and is widely employed in precision manufacturing, metrology laboratories, and quality assurance processes within industries such as aerospace, optics, and semiconductor equipment fabrication.
