Finished in Bright Brass, this hinge suits traditional and transitional door hardware sets. At 0.8 pounds, it is a single-unit hinge sold individually, sized at 5.25 inches long by 2.8 inches wide by 0.9 inches in height when measured as packaged.\u003c\/p\u003e\n\u003cp\u003eThis spring hinge is appropriate for interior and exterior door installations where self-closing function is required.

Adjust spring tension using the supplied tension pin before final installation, and ensure the door is fully powered down from any electrified hardware systems before beginning work. Verify that the hinge count and spring tension rating are appropriate for the door weight and width per applicable building and fire codes. Do not over-tension the spring, as this can cause premature wear on the hinge pivot and excessive door slam.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHinge Size\u003c\/strong\u003e: 4 x 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackaged Length\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackaged Width\u003c\/strong\u003e: 2.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackaged Height\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\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: DSH44U3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELTANA","offers":[{"title":"Default Title","offer_id":51559037894962,"sku":"DSH44U3","price":23.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a5e4b58e78a8febd4cd91c3887d4facb.jpg?v=1786426506","url":"https:\/\/voomisupply.com\/products\/deltana-dsh44u3-spring-hinge-4x4-bright-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
