It features a 0.25 inch outside diameter, a maximum work load of 4.56 pounds, and a spring rate of 0.81 lb\/in, making it well-suited for light-duty tensioning tasks. The wire diameter is 0.0317 inches and the spring carries a zinc-plated finish for corrosion resistance. Double loop ends provide secure attachment points in service assemblies. Technicians in HVAC, refrigeration, and general mechanical trades routinely stock small-format extension springs like the 414C for damper linkages, access panel latches, and equipment hardware repairs.\u003c\/p\u003e\n\u003cp\u003eThis extension spring is appropriate for use in residential and light commercial mechanical systems where a compact, low-force tensioning component is required. Typical applications include HVAC damper return mechanisms, control linkage tensioning, door or panel latch assemblies, and general equipment hardware. The 6.0 inch overall length and 4.56 inch maximum extended length accommodate a range of mounting spans without modification. The zinc-plated steel construction suits indoor and protected outdoor installations where light corrosion resistance is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.25 inch outside diameter with 0.0317 inch wire diameter for compact light-duty tensioning\u003c\/li\u003e\n  \u003cli\u003e4.56 lb maximum work load and 0.81 lb\/in spring rate for controlled, predictable tension\u003c\/li\u003e\n  \u003cli\u003eDouble loop end type provides secure, straightforward attachment to hooks or pins\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel finish offers corrosion resistance in typical indoor mechanical environments\u003c\/li\u003e\n  \u003cli\u003e6.0 inch overall length with 4.56 inch maximum extended length suits common damper and linkage spans\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement extension spring for light-duty mechanical assemblies requiring a 0.25 inch OD, double loop end configuration with a maximum work load of 4.56 pounds.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExtension springs should be installed by a qualified technician familiar with the host equipment. Always de-energize or shut down the associated system before replacing mechanical hardware components. Verify that the replacement spring rate and maximum load rating match the original specification before installation. Overstretching beyond the maximum extended length of 4.56 inches can permanently deform the spring and must be avoided.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 4.56 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 0.81 lb\/in\u003c\/li\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: 0.0317 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 4.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double Loop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.08 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: 414C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52083922403634,"sku":"414C","price":46.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e93ffa6e4a7c6c6bdb6896fd5e755522.jpg?v=1790057880","url":"https:\/\/voomisupply.com\/products\/gardner-spring-414c-extension-spring-0-25-in-od-4-56-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
