It has an outside diameter of 0.375 inches, a free length of 3.0 inches, and a maximum extended length of 6.84 inches. The wire diameter is 0.0348 inches, and the spring rate is 0.82 lb\/in, supporting a maximum work load of 3.8 pounds. The cross-over end style allows for straightforward hook engagement in standard spring anchor points. This part is typically installed by maintenance technicians, equipment assemblers, and trade professionals working on mechanical assemblies that require repeatable tension and return force.\u003c\/p\u003e\n\u003cp\u003eThe E35C is suited for residential and light commercial mechanical assemblies where a compact, consistent-rate extension spring is required. Common applications include HVAC equipment linkages, damper return mechanisms, small appliance assemblies, and general industrial hardware. The zinc-plated finish provides a basic level of corrosion resistance appropriate for indoor environments. This item is sold in a package quantity of three, making it practical for service kits and bench stock replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCross-over end style for standard hook and anchor point engagement\u003c\/li\u003e\n  \u003cli\u003eSpring rate of 0.82 lb\/in for predictable, linear tension response\u003c\/li\u003e\n  \u003cli\u003eMaximum work load of 3.8 pounds with a maximum extended length of 6.84 inches\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel construction for corrosion resistance in indoor use\u003c\/li\u003e\n  \u003cli\u003eCompact free length of 3.0 inches fits tight assembly envelopes\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 3 pieces for efficient stocking\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 mechanical assemblies requiring a 0.375-inch OD, 3.0-inch free length, cross-over end style spring with a 0.82 lb\/in spring rate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by maintenance technicians or mechanical assemblers using standard hand tools. Always de-energize or de-pressurize the host equipment before removing or installing any spring component. Verify that the replacement spring rate and maximum load rating match the original equipment specification before installation. Do not stretch the spring beyond its rated maximum extended length of 6.84 inches, as overextension can cause permanent deformation or failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 3.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 0.82 lb\/in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 6.84 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.0348 inches\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: 3 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: E35C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52073747644722,"sku":"E35C","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/725ae39bc37c6691118dadd2b043415e.jpg?v=1790050677","url":"https:\/\/voomisupply.com\/products\/gardner-spring-e35c-extension-spring-3-8-lb-max-load","provider":"Voomi Supply","version":"1.0","type":"link"}
