With an outside diameter of 0.375 inches and a wire diameter of 0.0475 inches, this spring delivers a maximum work load of 10.03 pounds and a spring rate of 3.77 pounds per inch. The overall free length is 3.0 inches, extending to a maximum of 5.03 inches under load. Cross-over end style allows for straightforward hook engagement in mechanical assemblies. Licensed technicians and maintenance professionals working with HVAC equipment, pumps, dampers, and related mechanical systems install this type of spring as a direct service replacement or in custom fabrication scenarios.\u003c\/p\u003e\u003cp\u003eThis extension spring suits residential and light commercial mechanical applications where a compact, corrosion-resistant tension spring is required. Common install scenarios include damper linkages, equipment access panels, tensioning assemblies, and other mechanical components that require a controlled return force. The plain finish over the stainless steel base material suits environments where moisture or chemical exposure is a concern. Sold in a package quantity of three units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStainless steel construction provides corrosion resistance for demanding environments\u003c\/li\u003e\n\u003cli\u003eCross-over end style for secure, low-profile hook engagement\u003c\/li\u003e\n\u003cli\u003eSpring rate of 3.77 lb\/in for predictable, consistent tension performance\u003c\/li\u003e\n\u003cli\u003eMaximum extended length of 5.03 inches from a 3.0-inch free length\u003c\/li\u003e\n\u003cli\u003eMaximum work load rated at 10.03 pounds\u003c\/li\u003e\n\u003cli\u003ePlain finish  -  no added coating that could affect dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-duty extension spring suitable for mechanical assemblies, damper linkages, and tensioning applications in HVAC, plumbing, and general trade equipment where a 0.375-inch OD cross-over end spring is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of extension springs should be performed by a qualified technician familiar with spring-loaded mechanical assemblies. Always de-energize and relieve any stored mechanical energy in the system before removing or installing springs. Use appropriate hand tools and eye protection, as extension springs store energy and can release suddenly if mishandled. Verify that the cross-over end hooks are fully seated in their mounting points before returning the assembly to service.\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: 3.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 5.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 10.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 3.77 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: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\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: 0.02 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: E42C-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":51989902000434,"sku":"E42C-SS","price":15.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f5d5bbd0cb4c172042ac3af3109a1e2_1061f96f-5526-4ad6-90ad-1de1d3129b97.jpg?v=1789988525","url":"https:\/\/voomisupply.com\/products\/gardner-spring-e42c-ss-extension-spring-0-375-in-od-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
