Rulers originate from 1500 BC, and since then were used in almost any sphere of human life. Modern day rulers are made from steel, wood, plastic, or glass. These tools vary in applications from small rulers used in schools for geometry and drawing to long industrial-grade rules. Line gages can also be compatible (like a carpenter's ruler) or flexible (like tape meters). We provide a wide selection of industrial precision and compatible rulers manufactured by the most famous brands.
