With an outside diameter of 0.375 inches and a wire diameter of 0.0475 inches, this spring delivers a spring rate of 9.69 pounds per inch and a maximum work load of 9.54 pounds. The overall free length is 1.75 inches, extending to a maximum of 2.49 inches under load. The cross-over end style allows for straightforward hook engagement in standard mounting configurations. Licensed trades and mechanical technicians working on HVAC equipment, control linkages, or panel assemblies will find this spring suited to low-force return and tensioning duties.\u003c\/p\u003e\u003cp\u003eThis extension spring is applicable in residential and light commercial settings where a compact, corrosion-resistant tensioning component is needed. The zinc-plated finish provides a basic level of corrosion protection suitable for indoor or sheltered mechanical environments. Cross-over ends accommodate inline pull loads and are commonly found in damper linkages, door latch mechanisms, and equipment panel hardware. Each package contains 3 pieces, making it practical for service stock or small-batch replacement work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCross-over end style for straightforward inline tensile engagement\u003c\/li\u003e\n\u003cli\u003eSpring rate of 9.69 pounds per inch for predictable, consistent force response\u003c\/li\u003e\n\u003cli\u003eMaximum work load rated at 9.54 pounds\u003c\/li\u003e\n\u003cli\u003eZinc-plated steel construction for basic corrosion resistance in sheltered environments\u003c\/li\u003e\n\u003cli\u003eCompact free length of 1.75 inches with maximum extended length of 2.49 inches\u003c\/li\u003e\n\u003cli\u003eSold in a 3-piece package to support service stock requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement extension spring for light-duty mechanical and HVAC-related tensioning applications requiring a 0.375 inch outside diameter cross-over end spring.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by mechanical technicians or HVAC service professionals. Disengage all power and relieve any stored mechanical energy in the assembly before removing or installing extension springs. Use appropriate hook tools or needle-nose pliers to seat cross-over ends securely; avoid overstretching the spring beyond its maximum extended length, as permanent deformation will affect spring rate and load performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.0475 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Free Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 2.49 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 9.69 lb\/in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 9.54 pounds\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: 0.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: E37C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52107740119346,"sku":"E37C","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d843940d739e0d16c250935495740d7_1dff2547-f2c4-4b42-994d-921f84b30881.jpg?v=1790074371","url":"https:\/\/voomisupply.com\/products\/gardner-spring-e37c-extension-spring-0-375in-od-9-54lb","provider":"Voomi Supply","version":"1.0","type":"link"}
