This Kapro aluminum rule has inch graduations to 1/16 and an anodized profile for measuring in woodworking, carpentry, and machining applications. Its graduations are UV (ultraviolet) cured screen printing and staggered in a height pattern for readability. It is made of anodized contractor-grade aluminum for durability. It has a hole in the end for hanging in a workspace or tool room. Rules are devices used to measure distances, or to rule straight lines. Rules have markings at specified intervals (also called graduations), as opposed to straight edges, which lack graduations and are used solely to draw a straight line. Nearly all rules are straight edges, except for rounded rules used to measure circles and arcs of angles in geometry applications. Rules can vary from high-quality steel instruments used by machinists; to retractable rules (also called tape measures) used in carpentry and for home-use; to simple wooden or plastic rules used in primary and secondary schools. Kapro manufactures spirit levels, laser levels, layout tools, and measuring tools. The company, founded in Israel in 1974, meets International Organization of Standardization (ISO) standards 9001, 14001, and SA8000.
