Ball-bearing knuckles reduce friction and wear under continuous use, making this hinge well suited for commercial and residential interior doors that see regular traffic. The hinge measures 4.5 inches by 4.5 inches, a standard full-mortise size accepted by most door prep cutouts in that dimension class. Installation is handled by finish carpenters, general contractors, or commercial door hardware technicians. The bright chrome finish provides a clean, polished appearance compatible with contemporary and traditional door hardware sets.\u003c\/p\u003e\n\u003cp\u003eThis hinge is appropriate for standard-weight interior door applications in both commercial and residential settings. It is sold individually and is typically used in pairs or sets of three depending on door height and weight requirements. The 4.5-inch leaf size suits commercial-grade hollow-metal or solid-wood door frames prepared to that specification. The bright chrome finish coordinates with matching IVES door trim, pulls, and protection plate products for a consistent hardware appearance across the opening.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFive-knuckle construction for added strength and alignment stability along the barrel\u003c\/li\u003e\n  \u003cli\u003eBall-bearing pivot points reduce friction and extend service life on frequently used doors\u003c\/li\u003e\n  \u003cli\u003eStandard-weight classification suitable for typical interior door applications\u003c\/li\u003e\n  \u003cli\u003e4.5-inch x 4.5-inch leaf dimensions fit common full-mortise door and frame preparations\u003c\/li\u003e\n  \u003cli\u003eBright chrome finish resists tarnish and coordinates with chrome architectural hardware sets\u003c\/li\u003e\n  \u003cli\u003eSold as individual units with a case quantity of 24 for project or stock purchasing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation hinge for standard full-mortise door preparations accepting a 4.5-inch x 4.5-inch hinge leaf.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by finish carpenters, commercial door hardware installers, or qualified general contractors. Remove the door from the opening and ensure all hinge mortises are clean and square before seating the leaves. Follow local building codes and door manufacturer guidelines for hinge quantity per door based on door height, weight, and fire-rating requirements. Do not overtighten fasteners into hollow-core door stiles, as this can strip the substrate and compromise hinge pull-through resistance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHinge Size\u003c\/strong\u003e: 4.5 inches x 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnuckle Count\u003c\/strong\u003e: Five\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Ball bearing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight Class\u003c\/strong\u003e: Standard weight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.5 inches (L) x 2.9 inches (W) x 1 inch (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSales Unit\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Quantity\u003c\/strong\u003e: 24\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: IVES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5BB1412651\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IVES","offers":[{"title":"Default Title","offer_id":51541836431666,"sku":"5BB1412651","price":25.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58f54fc1425a192548667265e28ba35c.jpg?v=1785886366","url":"https:\/\/voomisupply.com\/products\/ives-5bb1412651-ball-bearing-hinge-4-5x4-5-in-bright-chrome","provider":"Voomi Supply","version":"1.0","type":"link"}
