Measuring 4.5 inches by 4.5 inches, this hinge is finished in satin nickel and sold as a pair. Ball bearings provide smooth, consistent swing motion and reduce wear over repeated cycles. Licensed contractors and finish carpenters install this hardware on commercial and residential doors where a heavier-duty hinge is specified. The satin nickel finish delivers a clean, low-sheen appearance suited to modern and transitional door frames.\u003c\/p\u003e\n\u003cp\u003eThis hinge is appropriate for heavy interior and exterior doors in residential and light commercial settings. The square corner profile suits doors with square-cut mortises. At 4.5 inches, it is a common specification for solid-core wood doors, steel doors, and heavy flush doors where standard 3.5-inch hinges are undersized. Installers typically use this size on 1.75-inch thick door slabs requiring additional bearing capacity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.5 inches x 4.5 inches square hinge plate — fits standard heavy-duty door mortises\u003c\/li\u003e\n  \u003cli\u003eBall bearing construction for smooth, low-friction door operation\u003c\/li\u003e\n  \u003cli\u003eSatin nickel finish for a clean, understated appearance\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty build rated for high-cycle or weighted door applications\u003c\/li\u003e\n  \u003cli\u003eSold as a pair to match standard multi-hinge door installations\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 heavy-duty residential and light commercial doors requiring a 4.5-inch square corner hinge with a satin nickel finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a finish carpenter or licensed contractor. Power down any associated door hardware systems, such as electric strikes or access control devices, before servicing the door. Use a sharp chisel and appropriate mortise template to ensure a flush, square seat for the hinge leaf.
