Measuring 12 inches in overall length and 1 inch wide, this rule features a black chrome-plated finish over steel construction that reduces glare and improves readability in workshop and field conditions. The 3R graduation style provides three scales on a single edge, offering 1\/32, 1\/50, and 1\/64 inch increments. At 0.040 inches thick, it holds its shape without flex, making it reliable for layout work, scribe lines, and direct measurements on flat stock.\u003c\/p\u003e\n\u003cp\u003eThis rule is suited for machinists, pipefitters, sheet metal workers, and HVAC technicians who need a compact, accurate reference tool for layout and inspection tasks. The horizontal scale orientation makes it easy to read along a workpiece edge. The rigid format works well for scribing lines, checking cut lengths, and verifying dimensions on ductwork, conduit, piping, and mechanical components during fabrication or installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3R graduation style with three scales: 1\/32, 1\/50, and 1\/64 inch increments\u003c\/li\u003e\n  \u003cli\u003e12 inches overall length, 1 inch overall width\u003c\/li\u003e\n  \u003cli\u003eRigid construction holds shape for accurate scribing and layout\u003c\/li\u003e\n  \u003cli\u003eBlack chrome-plated finish reduces light glare for improved scale visibility\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop and field environments\u003c\/li\u003e\n  \u003cli\u003eNo hook, non-magnetic — straightforward layout tool with no added features to interfere with direct measurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose rigid steel rule suitable for use in machining, HVAC fabrication, plumbing layout, and electrical work where a compact 12-inch reference rule is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this measurement tool. Keep the rule clean and dry to preserve the black chrome-plated finish and prevent corrosion of the steel substrate. Avoid using the rule as a cutting guide with rotary or oscillating tools, as blade contact can damage graduation markings. Store flat or in a protective sleeve to maintain straightness and legibility of scales.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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: 0.0400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Style\u003c\/strong\u003e: 3R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Increments\u003c\/strong\u003e: 1\/32, 1\/50, 1\/64 inch\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\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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 13-895-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51716569104690,"sku":"13-895-8","price":25.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/791a48aaeb56dc2a4647ec429acf5452.jpg?v=1788528053","url":"https:\/\/voomisupply.com\/products\/spi-13-895-8-steel-rule-12-inch-3r-rigid-black-chrome","provider":"Voomi Supply","version":"1.0","type":"link"}
