Manufactured from spring steel with a satin chrome-plated finish, this rule measures 3 inches in overall length and 9\/16 inches in overall width, with a thickness of 0.05 inches. The 4R graduation style provides four scales in a single tool: 1\/16, 1\/32, 1\/64, and 1\/8 inch graduations. The horizontal scale orientation and rigid construction make it suitable for machinists, pipefitters, electricians, and HVAC technicians who need a compact, dependable reference rule for close-quarter measurements.\u003c\/p\u003e\u003cp\u003eThis short-format rule is well suited for bench work, parts layout, and inspection tasks where a full-length rule would be impractical. Its compact 3-inch length fits easily in a tool pouch or apron pocket, making it a practical carry item for field technicians. The satin chrome finish reduces glare under shop lighting, improving readability of fine graduation lines. It ships as a single unit and is appropriate for both individual tradespeople and shop tooling inventories.\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 inch\u003c\/li\u003e\n\u003cli\u003eRigid spring steel construction resists flexing during measurement\u003c\/li\u003e\n\u003cli\u003eSatin chrome-plated finish reduces glare and improves scale contrast\u003c\/li\u003e\n\u003cli\u003eCompact 3-inch length suited for tight-space and bench layout work\u003c\/li\u003e\n\u003cli\u003eHorizontal scale orientation for consistent left-to-right reading\u003c\/li\u003e\n\u003cli\u003eNon-magnetic, no hook included — straightforward layout rule\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard short-format rigid steel rule for general trade measurement and layout applications across mechanical, electrical, and HVAC disciplines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo installation is required for this hand tool. Store the rule in a dry location to prevent corrosion of the spring steel substrate beneath the chrome plating. Avoid using the rule as a straightedge for scoring or cutting, as blade contact can damage the graduation markings. Inspect graduation lines periodically for wear, particularly in high-use shop environments.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Spring 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\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.05 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 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\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Hook\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 56466\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542665724210,"sku":"56466","price":44.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2bad9da9a2e227037bb423782c27fbf7.jpg?v=1785904246","url":"https:\/\/voomisupply.com\/products\/starrett-56466-steel-rule-3-inch-4r-rigid","provider":"Voomi Supply","version":"1.0","type":"link"}
