Graduated in both decimal inch (1\/100 inch) and metric increments on a horizontal scale orientation, it delivers the dual-unit readability that machinists, pipefitters, HVAC fabricators, and sheet metal workers depend on. The satin chrome-plated finish reduces glare under shop lighting and resists corrosion from handling and shop-floor exposure. At 0.04 inches thick, the rule lies flat against work surfaces for accurate transfer measurements.\u003c\/p\u003e\u003cp\u003eThis rule is suited for general-purpose bench work, layout marking, and dimensional verification across light manufacturing, HVAC duct fabrication, plumbing rough-in, and mechanical trades. Its rigid construction eliminates flex during measurement, which matters when scribing lines on metal or checking cut lengths against a reference. The rule does not include a hook end and is not magnetic, making it a straightforward manual measuring tool for professionals who need a durable, no-frills reference rule at the bench or in the field.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual graduation system: decimal inch at 1\/100 inch intervals and metric scale for direct metric readings\u003c\/li\u003e\n\u003cli\u003eRigid construction holds shape under normal shop use without flex or bow\u003c\/li\u003e\n\u003cli\u003eSatin chrome plating reduces glare and provides corrosion resistance\u003c\/li\u003e\n\u003cli\u003eHorizontal scale orientation for easy left-to-right reading during layout work\u003c\/li\u003e\n\u003cli\u003e0.04-inch thickness allows flat contact with workpiece surfaces\u003c\/li\u003e\n\u003cli\u003eNo hook end and non-magnetic for simplified handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose rigid steel rule for trade and industrial measurement applications requiring decimal inch and metric dual-unit graduation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo installation is required for this measuring tool. Handle with clean, dry hands to preserve the satin chrome finish and prevent premature wear to graduation markings. Store flat or in a protective sleeve to avoid bending or surface scratches that can compromise measurement accuracy. This tool is intended for manual measurement use only and should not be used as a pry bar or cutting guide.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength (Metric)\u003c\/strong\u003e: 450 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0400 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation (Inch)\u003c\/strong\u003e: 1\/100 inch and 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation Style\u003c\/strong\u003e: Decimal and Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScale Orientation\u003c\/strong\u003e: Horizontal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Hook\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111604\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14-458-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692524994866,"sku":"14-458-4","price":55.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13f79a60c7540744a8f1d446c7cc74e3.jpg?v=1788298894","url":"https:\/\/voomisupply.com\/products\/spi-14-458-4-steel-rule-18-inch-decimal-metric-rigid","provider":"Voomi Supply","version":"1.0","type":"link"}
