Finished in satin chrome plating, it measures 6 inches overall in length and 3\/4 inches in width, with a thickness of 0.04 inches. The rule carries 5R graduation markings — 1\/100, 1\/32, and 1\/64 inch increments — making it suitable for layout work, machining setup, and inspection tasks that require multiple reference scales on a single tool. Licensed tradespeople, machinists, and field technicians who need a compact, non-flexible rule for close-tolerance work will find this a standard bench and toolbox addition.\u003c\/p\u003e\n\u003cp\u003eThis rule is suited for use in fabrication shops, HVAC unit assembly and measurement, plumbing rough-in layout, and electrical panel work where quick linear reference is needed. The horizontal scale orientation supports straightforward left-to-right reading. The rigid construction means it holds its shape under repeated use without bowing, which matters when scribing or marking cut lines on flat material. No hook is included, and the rule is non-magnetic.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5R graduation style with three scales: 1\/100, 1\/32, and 1\/64 inch increments\u003c\/li\u003e\n  \u003cli\u003eRigid construction — no flex — maintains straight-edge accuracy during layout\u003c\/li\u003e\n  \u003cli\u003eSatin chrome-plated finish reduces glare and resists corrosion\u003c\/li\u003e\n  \u003cli\u003eCompact 6-inch overall length fits toolboxes and apron pockets\u003c\/li\u003e\n  \u003cli\u003eHorizontal scale orientation for direct left-to-right reading\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in field and shop use\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 across trades including HVAC, plumbing, electrical, and light fabrication wherever a 6-inch precision measurement reference is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this measuring tool. Store flat to prevent warping or edge damage. When using for scribing or marking, ensure the rule is held flush against the workpiece surface to maintain measurement accuracy. Handle the satin chrome finish with care to avoid scratching, which can obscure graduation markings over time.\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: Satin Chrome-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 3\/4 inches\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: 5R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduations\u003c\/strong\u003e: 1\/100, 1\/32, 1\/64 inch\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\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: 13-842-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51717347901746,"sku":"13-842-0","price":23.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ffba09b6aa7003437a0543c93c9b1944.jpg?v=1788538909","url":"https:\/\/voomisupply.com\/products\/spi-13-842-0-steel-rule-6-inch-5r-rigid","provider":"Voomi Supply","version":"1.0","type":"link"}
