Adjust spring tension only with the tension adjustment pin supplied with the hinge, and set tension before fully seating all screws. On fire-rated door assemblies, verify that the hinge meets the required closing-force and label requirements per the applicable fire door assembly listing. Always confirm door weight and frequency of use are within the hinge rating before finalizing the installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Size\u003c\/strong\u003e: 4 inches x 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 2.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\/Thickness\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Flat Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSales Unit\u003c\/strong\u003e: Each\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: DSH4R51B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELTANA","offers":[{"title":"Default Title","offer_id":51559500579122,"sku":"DSH4R51B","price":23.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bcdf6e3f44f97169ea8c68d4673e2bab.jpg?v=1786434010","url":"https:\/\/voomisupply.com\/products\/deltana-dsh4r51b-spring-hinge-4x4-5-8-radius-flat-black","provider":"Voomi Supply","version":"1.0","type":"link"}
