It features a 0.187-inch outside diameter, a 0.023-inch wire diameter, and a spring rate of 1.56 pounds per inch. The E3C measures 1.75 inches in overall free length and extends to a maximum of 2.91 inches under a peak load of 2.33 pounds. This spring is typically installed by mechanical technicians, maintenance professionals, and assemblers working on precision equipment or light mechanical linkages where consistent tension and return force are required.\u003c\/p\u003e\n\u003cp\u003eThe E3C suits applications requiring a compact, low-force extension spring in tight spaces. Common use cases include door latches, light machinery, control linkages, and equipment panels in residential and commercial service environments. Its small wire diameter and modest load rating make it appropriate for applications where fine tension control is needed without excessive force. Sold in a package quantity of 12, it suits both single-unit repairs and small-batch production or maintenance kits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.187-inch outside diameter suits tight-clearance installations\u003c\/li\u003e\n  \u003cli\u003e1.56 lb\/in spring rate provides predictable, linear tension response\u003c\/li\u003e\n  \u003cli\u003e2.33 lb maximum work load rated for light-duty tensioning\u003c\/li\u003e\n  \u003cli\u003e1.75-inch free length extends to 2.91 inches at maximum load\u003c\/li\u003e\n  \u003cli\u003e0.023-inch wire diameter for precise, low-force applications\u003c\/li\u003e\n  \u003cli\u003eSold in packs of 12 for maintenance stock or batch assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-form extension spring suitable for light mechanical assemblies, control linkages, latches, and similar tensioning applications where a 0.187-inch OD, 1.75-inch free-length spring meets design requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExtension springs should be installed by qualified mechanical or maintenance technicians familiar with spring-loaded assemblies. De-energize or lock out any powered equipment before removing or installing springs to prevent unexpected movement. Use appropriate hook or loop engagement tools to avoid overstretching the spring beyond its maximum extended length of 2.91 inches, which can cause permanent deformation. Inspect hook ends for proper seating after installation to confirm secure retention.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.023 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 2.91 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 2.33 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 1.56 lb\/in\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: 0.05 pounds\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: E3C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52034534539570,"sku":"E3C","price":19.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ceae738dfba7fb0623d5731823ef4f1.jpg?v=1790022393","url":"https:\/\/voomisupply.com\/products\/gardner-spring-e3c-extension-spring-0-187in-od-2-33lb","provider":"Voomi Supply","version":"1.0","type":"link"}
