The Brown & Sharpe stainless steel rule measures workpieces in fractions of an inch. Stainless steel construction is durable and provides sharp graduation marks. Numbered graduations speed reading and reduce counting errors.
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.
Brown & Sharpe manufactures precision measuring equipment and metrology hand tools. The company, founded in 1833, is headquartered in North Kingstown, RI.
