It features a 0.36 inch outside diameter, a 0.049 inch wire diameter, and a spring rate of 15.74 pounds per inch. The initial tension is 1.04 pounds, and the maximum extended length is 1.04 inches. This spring suits applications in HVAC equipment, electrical controls, and light mechanical assemblies where a reliable, repeatable extension force is needed. Technicians and assemblers working with damper linkages, control panels, or small actuator mechanisms will find this spring a direct fit for standard-duty extension spring positions.\u003c\/p\u003e\u003cp\u003eThis extension spring is suited for use in residential and light commercial equipment where small-format springs are specified. Common installation scenarios include HVAC damper assemblies, electrical enclosure latches, control linkages, and similar mechanical components that require a spring to return a mechanism to a neutral or closed position. No specific model compatibility is stated by the manufacturer for this SKU. Package quantity is 3 springs per pack with a minimum order quantity of 1 pack.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.36 inch outside diameter for use in compact spring seats and guides\u003c\/li\u003e\n\u003cli\u003e0.049 inch wire diameter providing a 15.74 pounds per inch spring rate\u003c\/li\u003e\n\u003cli\u003e1.04 inch maximum extended length for short-travel extension applications\u003c\/li\u003e\n\u003cli\u003e1.04 pound initial tension delivers immediate resistive force at the start of extension\u003c\/li\u003e\n\u003cli\u003ePackaged in quantities of 3 for bench stock and service kit use\u003c\/li\u003e\n\u003cli\u003eUNSPSC Code 31161907 for procurement and catalog classification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement extension spring for compact mechanical assemblies in HVAC, electrical control, and light industrial equipment where a 0.36 inch OD extension spring with a 15.74 pounds per inch rate is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eExtension springs should be installed by a qualified technician familiar with the equipment being serviced. Always de-energize and lock out the equipment before removing or replacing springs in control linkages or actuator assemblies. Use appropriate pliers or spring hooks to seat the end loops without overstretching the spring beyond its rated maximum extended length. Overstretching an extension spring beyond its design limit will permanently reduce spring rate and initial tension.\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: 0.049 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 1.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 15.74 pounds per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial Tension\u003c\/strong\u003e: 1.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161907\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: 36-49-1370-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52103166230834,"sku":"36-49-1370-S","price":17.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0ee2fe6e36d01a34706113495f47573_f785bfc0-97ea-4f1c-8dcf-8a78ace6d819.jpg?v=1790071015","url":"https:\/\/voomisupply.com\/products\/gardner-spring-36-49-1370-s-extension-spring-0-36in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
