It features a 0.36-inch outside diameter, a 0.037-inch wire diameter, and a spring rate of 7.9 pounds per inch. The free length is 1 inch, and the maximum extended length is 1.68 inches. Initial tension is rated at 0.5 pounds. The plain finish indicates an uncoated carbon steel construction suited for dry or low-humidity environments. This spring is a standard catalog component stocked in quantities of 3 pieces per package.\u003c\/p\u003e\u003cp\u003eThis extension spring fits mechanical linkages, door and access panel latches, HVAC damper return mechanisms, electrical enclosure hardware, and similar assemblies where a compact, low-force extension spring is required. The 0.36-inch OD and 1-inch free length make it appropriate for confined mounting spaces typical in light commercial and residential equipment. Inside hook length is sized at a fractional 1-inch nominal, compatible with standard hook or loop retaining posts in OEM and aftermarket assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7.9 lb\/in spring rate provides consistent, predictable return force across the extension range\u003c\/li\u003e\n\u003cli\u003e0.36-inch outside diameter fits compact mechanical linkage slots and spring pockets\u003c\/li\u003e\n\u003cli\u003e1-inch free length extends to a maximum of 1.68 inches for controlled travel\u003c\/li\u003e\n\u003cli\u003e0.037-inch wire diameter delivers appropriate stiffness for low-load tensioning applications\u003c\/li\u003e\n\u003cli\u003ePlain finish for general-purpose dry-environment use\u003c\/li\u003e\n\u003cli\u003eSold in a 3-piece package  -  useful for service stock or small-quantity replacements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose catalog extension spring suitable for mechanical assemblies, equipment linkages, and OEM replacement applications requiring a 0.36-inch OD close-wound extension spring with a 7.9 lb\/in spring rate.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by mechanical or HVAC service technicians during equipment maintenance or component replacement. Relieve all tension from the assembly before removing the existing spring. Use appropriate pliers or spring hooks rated for the load to seat the spring hooks onto retaining posts without overextending the coils. Inspect the mating hook or post for wear or deformation before installing a new spring.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.037 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 1.68 inches (42.67 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 7.9 lb\/in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial Tension\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Hook Length\u003c\/strong\u003e: 1 inch (fractional nominal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\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: 0.4 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: GE0360-037-1000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52089586745650,"sku":"GE0360-037-1000","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8f88cbaefd259f819bb2c0082fc02b5.jpg?v=1790061943","url":"https:\/\/voomisupply.com\/products\/gardner-spring-ge0360-037-1000-extension-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
