It features a 1.375-inch outside diameter, a wire diameter of 0.207 inches, and an overall length of 8.75 inches. With a maximum work load of 174 lb and a spring rate of 145 lb\/in, this spring is built for demanding load-bearing environments. A galvanized, zinc-plated finish provides corrosion resistance for use in exposed or high-humidity settings. This package contains 3 pieces.\u003c\/p\u003e\n\u003cp\u003eThis extension spring is suited for use in manufacturing equipment, agricultural machinery, garage door assemblies, industrial controls, and other mechanical systems that require reliable tensile force. The combination of high load capacity and a firm spring rate makes it appropriate for applications where consistent return force and fatigue resistance are priorities. Installation is typically performed by maintenance technicians, millwrights, or mechanical contractors familiar with spring-loaded assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e174 lb maximum work load supports heavy tensile-force applications\u003c\/li\u003e\n  \u003cli\u003eSpring rate of 145 lb\/in provides firm, predictable deflection response\u003c\/li\u003e\n  \u003cli\u003e1.375-inch outside diameter and 0.207-inch wire diameter for robust construction\u003c\/li\u003e\n  \u003cli\u003e8.75-inch overall length suits a range of mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eGalvanized, zinc-plated steel finish for corrosion resistance in harsh environments\u003c\/li\u003e\n  \u003cli\u003eSold as a package of 3 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit extension spring for industrial and mechanical assemblies requiring a 1.375-inch OD spring with a 174 lb load rating and 145 lb\/in spring rate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExtension springs store energy under tension and must be handled carefully during installation to prevent sudden release. Always relieve all tension from the assembly before removing or installing the spring. Use proper spring installation tools and wear appropriate personal protective equipment, including eye protection. Verify that mounting hooks or end fittings are rated for the spring load before putting the assembly back into service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 174 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 145 lb\/in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.207 inches\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\u003eNumber of Pieces\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 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: 377\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52015483715890,"sku":"377","price":39.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36dbc93c589f6f445e35d17f250bee89.jpg?v=1790007845","url":"https:\/\/voomisupply.com\/products\/gardner-spring-377-extension-spring-174-lb-1-375-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
