Finished in black chrome plating for improved contrast and corrosion resistance, this rule reads clearly against both light and dark workpiece surfaces. It measures 12 inches overall in length and 1 inch in width, with a thickness of 0.04 inches. The 4R graduation style provides four scales on a single rule, giving technicians and tradespeople multiple reference increments without switching tools. Machinists, pipefitters, HVAC installers, and sheet metal workers commonly use this type of rule for layout, measurement verification, and component fitting.\u003c\/p\u003e\u003cp\u003eThis rule suits general layout and measurement tasks in residential and commercial settings. It is well suited to shop benches, field service kits, and job-site toolboxes wherever a durable, easy-to-read steel rule is needed. The rigid construction prevents flex during measurement, supporting accurate readings on flat and curved surfaces alike. The horizontal scale orientation supports straightforward left-to-right reading in standard measurement workflows.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4R graduation style with four scales: 1\/16, 1\/32, 1\/64, and 1\/8 inches\u003c\/li\u003e\n\u003cli\u003eBlack chrome-plated finish improves scale contrast and resists corrosion\u003c\/li\u003e\n\u003cli\u003eRigid construction prevents flex for consistent, repeatable measurements\u003c\/li\u003e\n\u003cli\u003e12 inches overall length and 1 inch width in a compact, portable profile\u003c\/li\u003e\n\u003cli\u003eNo hook or magnetic features — straightforward layout and measurement tool\u003c\/li\u003e\n\u003cli\u003eHorizontal scale orientation for standard left-to-right reading\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose steel rule suitable for machinists, pipefitters, HVAC technicians, sheet metal workers, and other trade professionals requiring precise inch-based linear measurement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo installation is required for this hand tool. Store in a protective sleeve or toolbox slot to prevent surface scratches that can reduce scale readability. Clean periodically with a dry or lightly oiled cloth to maintain the chrome finish and prevent surface oxidation. Handle carefully to avoid bending, as rigid rules are not designed to flex and may deform under excessive lateral force.\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\u003eCoating\/Finish\u003c\/strong\u003e: Black Chrome-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation Style\u003c\/strong\u003e: 4R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduations\u003c\/strong\u003e: 1\/16, 1\/32, 1\/64, 1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScale Orientation\u003c\/strong\u003e: Horizontal\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\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: 13-896-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692508217650,"sku":"13-896-6","price":25.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd952770e63016ec08305cc97e8e99aa.jpg?v=1788298614","url":"https:\/\/voomisupply.com\/products\/spi-13-896-6-steel-rule-12-inches-4r-rigid","provider":"Voomi Supply","version":"1.0","type":"link"}
