With an outside diameter of 0.437 inches and a wire diameter of 0.0475 inches, this spring delivers a spring rate of 1.62 lb\/in and supports a maximum work load of 8.5 pounds. The overall free length is 4 inches, extending to a maximum of 8.25 inches under load. It is suited for installation by maintenance technicians, mechanical assemblers, and trade professionals working on equipment requiring precise tension control.\u003c\/p\u003e\u003cp\u003eThis extension spring is appropriate for use in residential and light commercial mechanical assemblies where consistent return force is needed. Typical applications include HVAC damper linkages, door and panel latching mechanisms, and general equipment tensioning systems. The 0.437-inch OD and 1.62 lb\/in spring rate make it a practical fit for compact mechanical spaces where a small-diameter, moderate-load spring is specified. This product is sold in packages of 6 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOutside diameter of 0.437 inches for compact fitment in tight assemblies\u003c\/li\u003e\n\u003cli\u003eSpring rate of 1.62 lb\/in for predictable, linear tension response\u003c\/li\u003e\n\u003cli\u003eMaximum work load of 8.5 pounds for light-duty tensioning applications\u003c\/li\u003e\n\u003cli\u003eFree length of 4 inches, extending to 8.25 inches at maximum load\u003c\/li\u003e\n\u003cli\u003eWire diameter of 0.0475 inches for fine-gauge, precision spring performance\u003c\/li\u003e\n\u003cli\u003eSold in a package of 6 pieces to support replacement inventory needs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose extension spring suitable for mechanical assemblies requiring a 0.437-inch OD spring with a 1.62 lb\/in spring rate and up to 8.5 pounds of maximum work load.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eExtension springs store energy under tension and should be installed and removed with appropriate hand tools while the connected assembly is de-energized or de-pressurized. Verify that the mounting hooks or anchor points match the spring end configuration before installation. Wear eye protection when handling extension springs, as sudden release can cause injury. Follow applicable equipment manufacturer service documentation and any relevant mechanical codes for the host assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 8.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 1.62 lb\/in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.437 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\u003eFree Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 8.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: E49C-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52082279252274,"sku":"E49C-SS","price":26.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f5d5bbd0cb4c172042ac3af3109a1e2_a0f2bc18-7592-4bed-97d9-b9ef408496e4.jpg?v=1790056674","url":"https:\/\/voomisupply.com\/products\/gardner-spring-e49c-ss-extension-spring-8-5-lb-0-437-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
