With a maximum work load of 3.01 pounds and a spring rate of 0.74 lb\/in, this spring delivers consistent, measured tension through its full stroke. It measures 4 inches in overall length and extends to a maximum of 7.18 inches, with an outside diameter of 0.210 inches and a wire diameter of 0.0258 inches. A zinc-plated, galvanized finish provides corrosion resistance for use in both indoor and moderately humid service environments. Technicians in HVAC, plumbing, electrical, and general equipment maintenance will encounter this style of extension spring in control linkages, damper assemblies, and actuator return mechanisms.\u003c\/p\u003e\n\u003cp\u003eThe V13C is suited for residential and light commercial applications where a small-diameter, low-load extension spring is required. Common installation scenarios include HVAC damper linkages, electrical panel latching mechanisms, small actuator assemblies, and other control components that require consistent return tension. Its compact outside diameter and extended length range make it appropriate for confined mounting locations where larger springs cannot be accommodated. Each unit is sold individually, with a package quantity of 12 available.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum work load of 3.01 pounds for light-duty tensioning applications\u003c\/li\u003e\n  \u003cli\u003eSpring rate of 0.74 lb\/in provides predictable, linear force across the stroke\u003c\/li\u003e\n  \u003cli\u003eExtends from 4 inches overall length to a maximum of 7.18 inches\u003c\/li\u003e\n  \u003cli\u003e0.210 inches outside diameter fits confined mounting locations\u003c\/li\u003e\n  \u003cli\u003eGalvanized, zinc-plated steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eInitial tension of 0.60 pounds maintains coil closure before load is applied\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement extension spring for light-duty mechanical, HVAC control, and equipment service applications requiring a 0.210-inch OD, 4-inch body length spring with a 0.74 lb\/in spring rate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExtension springs should be installed by a qualified technician familiar with the equipment assembly being serviced. Always de-energize or shut down the equipment and relieve any existing spring tension before removing or installing springs. Use appropriate hooking tools to seat the spring ends securely to mounting points without overextending the coils beyond the stated maximum extended length of 7.18 inches. Overextension beyond the rated maximum load can cause permanent set or spring failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.210 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.0258 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 7.18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 0.74 lb\/in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 3.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial Tension\u003c\/strong\u003e: 0.60 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Galvanized, Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: V13C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":51996015919410,"sku":"V13C","price":36.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ba871dbfc50dc545e26a501d56b33cd.jpg?v=1789993076","url":"https:\/\/voomisupply.com\/products\/gardner-spring-v13c-extension-spring-3-01-lb-4-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
