Spring hinges use an internal coil mechanism to automatically return a door to a closed position after each use, replacing the need for a separate door closer on lighter interior doors. This hinge is sold as a single unit and is intended for standard residential and light commercial door installations. The satin nickel finish provides a clean, low-sheen appearance suited to modern and transitional hardware sets. Installation is performed by carpenters, finish contractors, or experienced maintenance trades.\u003c\/p\u003e\n\u003cp\u003eThe DSH35U15 is appropriate for interior passage doors where self-closing function is required by code or desired for convenience, such as doors leading to garages, mechanical rooms, or utility spaces. The 3.5 x 3.5 inch leaf size fits standard residential door preparations and pairs with common door thicknesses found in residential framing. The satin nickel finish coordinates with U15-designated door hardware throughout a project for a consistent appearance across knobs, levers, and hinges.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSelf-closing spring mechanism returns door to closed position without a separate closer\u003c\/li\u003e\n  \u003cli\u003e3.5 x 3.5 inch leaf size fits standard residential door preparations\u003c\/li\u003e\n  \u003cli\u003eSatin nickel (U15) finish for consistent hardware coordination across a project\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit, allowing replacement of individual hinges as needed\u003c\/li\u003e\n  \u003cli\u003eCompact profile: 5.25 inches length, 2.5 inches width, 0.8 inches height when measured in package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation spring hinge for standard residential interior doors requiring a self-closing function at a 3.5 x 3.5 inch hinge prep.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSpring hinges are installed by carpenters or finish contractors and typically require a tension adjustment after mounting to set the closing speed and latching force. Before replacing an existing hinge, remove the door from the frame and ensure the mortise dimensions match the 3.5 x 3.5 inch leaf size. Consult local building codes, including IBC or IRC requirements, when installing self-closing hardware on fire-rated or code-required self-closing door assemblies. Use the manufacturer-supplied tension pin or hex tool to adjust spring tension after installation; do not over-tension the spring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Size\u003c\/strong\u003e: 3.5 x 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Nickel (U15)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSales Unit\u003c\/strong\u003e: Each (EA)\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: DELTANA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DSH35U15\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELTANA","offers":[{"title":"Default Title","offer_id":51559087505714,"sku":"DSH35U15","price":21.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d777865b7369b19152bba9563f2ea68.jpg?v=1786427101","url":"https:\/\/voomisupply.com\/products\/deltana-dsh35u15-spring-hinge-3-5x3-5-inches-satin-nickel","provider":"Voomi Supply","version":"1.0","type":"link"}
