Constructed from durable spring steel with a nickel-plated finish, this spring handles a maximum safe load of 46.2 pounds and a maximum deflection of 0.95 inches. The outside diameter is 0.75 inches, inside diameter is 0.5 inches, overall length is 2.875 inches, and wire diameter is 0.105 inches. The corrosion-resistant finish makes these springs suitable for both indoor and outdoor use. Each package contains two springs.\u003c\/p\u003e\n\u003cp\u003eThese closed extension springs are a practical choice for general maintenance and repair tasks handled by HVAC technicians, plumbers, maintenance mechanics, and experienced handymen. Typical applications include door hardware, screen door closers, light-duty tensioning assemblies, and similar mechanical linkage systems where a compact extension spring with predictable load characteristics is required. The nickel-plated coating adds resistance to moisture and mild corrosive environments, extending service life in exposed locations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpring steel construction provides consistent tensile strength across repeated load cycles\u003c\/li\u003e\n  \u003cli\u003eNickel-plated finish resists corrosion for indoor and outdoor applications\u003c\/li\u003e\n  \u003cli\u003eMaximum safe load of 46.2 pounds with maximum deflection of 0.95 inches\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 0.75 inches and overall length of 2.875 inches for compact fitment\u003c\/li\u003e\n  \u003cli\u003eSingle-loop closed end design for straightforward hook or pin attachment\u003c\/li\u003e\n  \u003cli\u003eTwo springs included per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose closed extension spring suitable for door hardware, light mechanical assemblies, and similar residential or light commercial tensioning applications where a 0.75-inch OD extension spring is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExtension springs store energy under tension and should be handled with care during installation and removal. Relieve all tension from the assembly before disconnecting or connecting the spring. Use appropriate pliers or hook tools to seat the single-loop ends onto mounting pins or hooks without overstretching. Do not exceed the rated maximum safe load of 46.2 pounds during service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Safe Load\u003c\/strong\u003e: 46.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 0.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.105 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single-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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.57 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 9619\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRIME-LINE","offers":[{"title":"Default Title","offer_id":51559706067250,"sku":"SP 9619","price":21.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9bf9e2c3746687470235845c928075f.jpg?v=1786438661","url":"https:\/\/voomisupply.com\/products\/prime-line-products-sp-9619-closed-extension-spring-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
