Constructed from durable spring steel with a nickel-plated finish, this spring resists corrosion and provides reliable tensile return force in light-duty service. The 3\/8-inch outer diameter and 2.05-inch deflection length make it well suited for applications where a compact, consistent spring rate is needed. Each package contains 3 springs, supplying spares for high-turnover repair stock. This part is typically installed by maintenance technicians, handymen, and knowledgeable DIYers working on mechanical assemblies that require extension spring action.\u003c\/p\u003e\n\u003cp\u003eExtension springs of this type appear in a wide range of residential and light commercial settings, including door hardware, screen doors, cabinet mechanisms, small appliance linkages, and general mechanical assemblies. The double loop closed end design allows straightforward hook attachment to anchor points without additional hardware. The nickel-plated finish provides a measure of surface protection in low-moisture indoor environments. The 3-unit pack is suitable for single repairs with backup units on hand or for batch servicing of multiple identical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble loop closed end design for direct hook-to-anchor attachment\u003c\/li\u003e\n  \u003cli\u003eSpring steel construction for consistent return force and fatigue resistance\u003c\/li\u003e\n  \u003cli\u003eNickel-plated finish for corrosion resistance in indoor applications\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch outer diameter fits compact spring seat locations\u003c\/li\u003e\n  \u003cli\u003e2.05-inch deflection length supports a range of light-duty tension applications\u003c\/li\u003e\n  \u003cli\u003eSold in a 3-pack for backup inventory or batch repairs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement extension spring for residential and light commercial hardware assemblies requiring a 3\/8-inch OD double loop closed end spring.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExtension springs store energy under tension and should be installed and removed with appropriate hand protection to prevent injury if a loop slips. Relieve all load from the existing spring before removal. Use needle-nose pliers or a spring hook tool to seat the loops onto anchor points without overstretching the spring body. Verify that the replacement spring deflection length and end-loop orientation match the original assembly before applying load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDeflection Length\u003c\/strong\u003e: 2.05 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double Loop Closed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Spring Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Nickel-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 3 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.11 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: PRIME LINE PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SP 9673\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRIME-LINE","offers":[{"title":"Default Title","offer_id":51558020120882,"sku":"SP 9673","price":16.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87491eed9c20acda251fe45ff3f26619.jpg?v=1786401048","url":"https:\/\/voomisupply.com\/products\/prime-line-products-sp-9673-extension-spring-3-8-in-od-3-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
