It measures 12 inches in overall length and 1\/2 inch in overall width, with a thickness of 0.0200 inches that allows it to flex and conform to curved or irregular surfaces. The rule features a 4R graduation style, providing four scales on a single blade: 1\/16, 1\/32, 1\/64, and 1\/8 inch increments. A black chrome-plated finish reduces glare and improves contrast on the black-finished blade, making graduation marks easier to read in variable lighting conditions. Licensed trades and precision-oriented technicians rely on this type of rule for scribing, layout, and checking measurements on tight or curved workpieces.\u003c\/p\u003e\u003cp\u003eThis flexible steel rule suits general trade use across HVAC, plumbing, electrical, and mechanical service work wherever a rigid rule cannot seat flat against a surface. The horizontal scale orientation and fine graduation increments make it well suited for applications requiring readings down to 1\/64 inch. It is sold individually and requires no special tools or accessories for immediate use out of the package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFlexible blade conforms to curved or uneven surfaces for accurate contact measurement\u003c\/li\u003e\n\u003cli\u003e4R graduation style provides four scales: 1\/16, 1\/32, 1\/64, and 1\/8 inch\u003c\/li\u003e\n\u003cli\u003eBlack chrome-plated finish reduces light glare and improves scale visibility\u003c\/li\u003e\n\u003cli\u003e0.0200 inch blade thickness allows flex without permanent deformation under normal use\u003c\/li\u003e\n\u003cli\u003eHorizontal scale orientation for straightforward left-to-right reading\u003c\/li\u003e\n\u003cli\u003eNo hook included — clean end profile for butt-end and edge measurements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose flexible steel rule suitable for standard layout and measurement tasks across trade and industrial applications.

Store the rule flat or in a protective sleeve to prevent permanent bending or surface damage to the graduation markings. Avoid using the rule as a cutting guide with utility knives, as scoring the blade surface can degrade graduation legibility over time. Clean with a dry cloth after use in oily or wet environments to preserve the chrome-plated finish.\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\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation Style\u003c\/strong\u003e: 4R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation Increments\u003c\/strong\u003e: 1\/16, 1\/32, 1\/64, and 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Flexible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScale Orientation\u003c\/strong\u003e: Horizontal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHook Included\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 13-916-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51690359947570,"sku":"13-916-2","price":23.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60f121c719065fad35971064d148a2c5.jpg?v=1788269415","url":"https:\/\/voomisupply.com\/products\/spi-13-916-2-flexible-steel-rule-12-inch-4r","provider":"Voomi Supply","version":"1.0","type":"link"}
