It features a 0.25-inch outside diameter, a 2.0-inch overall length, and a maximum extended length of 3.64 inches. The spring is rated for a maximum work load of 3.35 pounds and carries a spring rate of 1.64 pounds per inch. The wire diameter is 0.0286 inches. A zinc-plated finish provides basic corrosion resistance. Cross-over end hooks allow for straightforward loop attachment in standard spring seats and anchor points. This spring is installed by mechanical technicians and maintenance professionals working on equipment that requires controlled tension or return force.\u003c\/p\u003e\u003cp\u003eThe E11C is suited for light mechanical assemblies found in HVAC equipment, electrical enclosures, plumbing fixtures, and general industrial or commercial hardware. Its compact form factor and cross-over end style make it a practical fit for confined mounting spaces where a small-profile tension spring is required. It is sold in packages of 12, making it appropriate for service technicians who stock common spring sizes for field repairs or bench assembly work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.25-inch outside diameter for compact installation in tight clearances\u003c\/li\u003e\n\u003cli\u003e3.35-pound maximum work load with a 1.64 lb\/in spring rate for predictable tensioning\u003c\/li\u003e\n\u003cli\u003e3.64-inch maximum extended length provides controlled extension range\u003c\/li\u003e\n\u003cli\u003eCross-over end hooks allow secure loop-to-anchor attachment\u003c\/li\u003e\n\u003cli\u003eZinc-plated steel construction offers basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSold in a 12-piece package  -  practical for service stock\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-profile small-diameter extension spring suitable for light mechanical assemblies requiring a 0.25-inch OD cross-over hook spring with a 2.0-inch free length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eExtension springs store energy under tension and should be installed and removed using appropriate hand tools to prevent snap-back injury. Always de-energize or depressurize the assembly before servicing spring-loaded components. Verify that anchor points and loop seats are free of burrs or sharp edges that could cause premature fatigue at the hook. Confirm the installed load does not exceed the 3.35-pound maximum work load rating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 3.64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.0286 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 3.35 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 1.64 lb\/in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Cross-Over\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: E11C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52016569680178,"sku":"E11C","price":21.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c7580e0a36e4900b6588aba72046661.jpg?v=1790008777","url":"https:\/\/voomisupply.com\/products\/gardner-spring-e11c-extension-spring-0-25-in-od-3-35-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
