Measuring 36 inches in overall length and 1-1\/4 inches in overall width, it features a 4R graduation pattern with four scales: 1\/16, 1\/32, 1\/64, and 1\/8 inch increments. The rule is made from spring steel with a satin chrome-plated finish that reduces glare and resists corrosion. At 0.050 inches thick, it maintains a rigid profile that stays flat against a workpiece. Machinists, pipefitters, fabricators, and HVAC sheet metal technicians rely on this type of rule for layout and inspection work.\u003c\/p\u003e\n\u003cp\u003eThis rule is suited for use in fabrication shops, mechanical rooms, plumbing rough-in, and HVAC ductwork layout where precise linear measurement is required over longer spans. The horizontal scale orientation makes it straightforward to read when laying out cuts or checking dimensions on flat stock. The 36-inch length covers full-yard measurements without extension, reducing the chance of cumulative error across multiple shorter rule placements. It is not magnetic and does not include a hook end, making it a direct-reading layout tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e36-inch overall length covers full-yard measurements in a single placement\u003c\/li\u003e\n  \u003cli\u003e4R graduation pattern includes 1\/16, 1\/32, 1\/64, and 1\/8 inch scales\u003c\/li\u003e\n  \u003cli\u003eSpring steel construction maintains rigidity across the full length\u003c\/li\u003e\n  \u003cli\u003eSatin chrome-plated finish reduces glare and resists surface corrosion\u003c\/li\u003e\n  \u003cli\u003e0.050-inch thickness provides a stable, flat reading edge\u003c\/li\u003e\n  \u003cli\u003eNon-magnetic, no-hook design for straightforward direct-reading layout use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose rigid steel rule for professional layout, fabrication, and inspection applications requiring a 36-inch graduated measuring tool.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this hand tool. Keep the rule clean and dry to preserve the satin chrome finish and maintain legibility of the graduation markings. Avoid storing it in contact with abrasive surfaces that could scratch the scales. Inspect graduation markings periodically for wear if the rule is used in high-frequency production environments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Spring Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Style\u003c\/strong\u003e: 4R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Scales\u003c\/strong\u003e: 1\/16, 1\/32, 1\/64, 1\/8 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\u003eColor\u003c\/strong\u003e: Silver\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: 0.625 pounds\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 52682\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539554992434,"sku":"52682","price":314.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c60c6dfed7a1171d679d39fc1916e705.jpg?v=1785842980","url":"https:\/\/voomisupply.com\/products\/starrett-52682-steel-rule-36in-4r-graduation-rigid","provider":"Voomi Supply","version":"1.0","type":"link"}
