With an outside diameter of 0.25 inches and a wire diameter of 0.0286 inches, this spring delivers a spring rate of 1.45 lb\/in and supports a maximum work load of 3.37 pounds. The overall free length is 2.25 inches, extending to a maximum of 4.1 inches under load. Cross-over end style ensures straightforward installation and repeatable alignment in close-tolerance assemblies. This spring is suited for use in HVAC equipment, electrical panels, light mechanical linkages, and general trade service applications where a compact extension spring is required.\u003c\/p\u003e\n\u003cp\u003eThe E12C is appropriate for residential and light commercial applications where small-format extension springs are needed for actuator arms, damper linkages, door latches, panel covers, or other tension-return mechanisms. The zinc plating provides corrosion resistance suitable for indoor mechanical environments. Sold in a package of 12 pieces, this spring is well suited for service technicians who need on-hand replacements for common light-duty tension spring positions across multiple equipment types.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCross-over end style for reliable alignment and easy hook engagement\u003c\/li\u003e\n  \u003cli\u003eSpring rate of 1.45 lb\/in for predictable, consistent tension across the load range\u003c\/li\u003e\n  \u003cli\u003eMaximum work load of 3.37 pounds with a maximum extended length of 4.1 inches\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel construction for corrosion resistance in indoor mechanical environments\u003c\/li\u003e\n  \u003cli\u003eCompact 0.25 inch outside diameter fits tight spaces and small-format spring pockets\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 12, suitable for stocking service vans and shop inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service stock extension spring for light-duty mechanical assemblies requiring a 0.25 inch OD, cross-over end style spring with a 1.45 lb\/in spring rate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExtension springs should be installed and replaced by qualified mechanical or trade service technicians. Always de-energize or shut down the equipment and relieve any existing spring tension before removing or installing tension springs. Use appropriate spring installation tools to avoid overextending the spring beyond the maximum extended length of 4.1 inches, which can cause permanent deformation or failure. Inspect hook and anchor points for wear or damage before installing a replacement spring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.0286 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Free Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 4.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 3.37 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 1.45 lb\/in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Cross-Over\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: GARDNER SPRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E12C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52074897801522,"sku":"E12C","price":21.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a94a105152c6a240f5445c7d5136ba2.jpg?v=1790051488","url":"https:\/\/voomisupply.com\/products\/gardner-spring-e12c-extension-spring-0-25-in-od-zinc-plated","provider":"Voomi Supply","version":"1.0","type":"link"}
