Built for demanding applications, it features a ball bearing mechanism that reduces friction and supports smooth, consistent door operation over extended use. The paint black finish provides a clean, uniform appearance suited to both interior and exterior door installations. This hinge is sold as a pair and is typically installed by carpenters, contractors, or door hardware technicians working on commercial or residential projects requiring a durable, high-cycle hinge solution.\u003c\/p\u003e\n\u003cp\u003eThe S44R4HDB1B is appropriate for use on heavy interior or exterior doors where a standard hinge would be undersized. The heavy-duty construction and ball bearing design make it well-suited for high-traffic doorways in commercial buildings, multi-family residential properties, and institutional settings. The radius corner geometry fits standard door frame mortises cut for 4 x 4 inch hinges. Each unit ships as a pair, allowing a two-hinge installation on a single door with one order quantity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4 inch x 4 inch leaf size with 0.25 inch radius corners for standard mortise compatibility\u003c\/li\u003e\n  \u003cli\u003eBall bearing construction reduces operational friction and extends service life on heavy or high-cycle doors\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty rating supports solid core and heavier door assemblies\u003c\/li\u003e\n  \u003cli\u003ePaint black finish provides a consistent, low-sheen appearance that accepts touch-up paint if needed\u003c\/li\u003e\n  \u003cli\u003eSold as a pair — one order quantity equals two hinges\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 doors mortised to accept a 4 inch x 4 inch radius corner hinge plate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed carpenter or door hardware technician using a chisel, mallet, and drill with appropriate bit sizes for the fastener pattern. Remove the door from the frame and secure it safely before beginning hinge work. Ensure the mortise depth matches the hinge leaf thickness to achieve a flush mount and proper door clearance.
