It features a 3\/16 inch outside diameter (0.1870 inches decimal), a 0.026 inch wire diameter, and a spring rate of 6.1 lb\/in. The maximum work load is 4.3 pounds with a maximum extended length of 1.62 inches. This spring is sold in a package quantity of six, making it suitable for service stock and multi-unit repair jobs. Licensed tradespeople and maintenance technicians working on equipment with small spring-return mechanisms will find this part a direct fit for standard light-duty roles.\u003c\/p\u003e\u003cp\u003eThe 37030G is used in residential and light commercial applications where a compact extension spring is required to maintain tension, close a damper, return a lever arm, or hold a component under consistent load. Its 1 inch free length and inside hook configuration make it compatible with standard spring-hook mounting points found in HVAC damper linkages, control panel doors, and mechanical latching assemblies. This spring ships in packs of six, supporting both single-unit repairs and batch maintenance schedules.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/16 inch outside diameter with 0.026 inch wire diameter for precision light-duty tensioning\u003c\/li\u003e\n\u003cli\u003e6.1 lb\/in spring rate provides consistent, predictable return force\u003c\/li\u003e\n\u003cli\u003eMaximum work load of 4.3 pounds with maximum extended length of 1.62 inches\u003c\/li\u003e\n\u003cli\u003e1 inch free length with inside hook ends for standard hook-mount installations\u003c\/li\u003e\n\u003cli\u003eSold in a package of six for service stock efficiency\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 assemblies requiring a 3\/16 inch OD, 1 inch free length spring with inside hook ends.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by HVAC technicians, mechanical service technicians, or licensed tradespeople during equipment maintenance or damper repair. Always de-energize and lock out equipment before replacing spring components. Use appropriate pliers or spring hooks rated for the work load to avoid over-stretching the spring beyond its maximum extended length of 1.62 inches, which can cause permanent deformation. Follow equipment manufacturer procedures for spring attachment points and hook engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.1870 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.026 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 1.62 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 6.1 lb\/in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 4.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Inside Hook\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: 0.02 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: 37030G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52027944796466,"sku":"37030G","price":29.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44ba52e31dec7bf784d0a03a2203375e_e867c525-ef95-4fbe-8ed7-d8d30d18fde4.jpg?v=1790017425","url":"https:\/\/voomisupply.com\/products\/gardner-spring-37030g-extension-spring-3-16-in-od-4-3-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
