Measuring 4 inches by 4 inches with a 1\/4-inch radius corner profile, this hinge suits standard full-mortise door applications. The flat black finish provides a clean, uniform appearance compatible with modern and transitional architectural styles. Sold as a pair, it is typically installed by carpenters, finish contractors, and door hardware specialists working on interior or exterior door frames requiring a heavier-gauge hinge.\u003c\/p\u003e\u003cp\u003eThis hinge is suited for residential and light-commercial door installations where a heavy-duty hinge is specified. The 4 inches x 4 inches leaf size covers standard door thicknesses and widths commonly found in entry, passage, and utility door applications. The 1\/4-inch radius corner allows drop-in replacement or new installation in mortise preparations routed to that corner specification. Installers working on high-traffic doors or solid-core door slabs will benefit from the heavy-duty construction rating.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 inches x 4 inches leaf size suited for standard and solid-core door applications\u003c\/li\u003e\n\u003cli\u003e1\/4-inch radius corner profile for mortise compatibility\u003c\/li\u003e\n\u003cli\u003eHeavy-duty construction for high-cycle or high-traffic door use\u003c\/li\u003e\n\u003cli\u003eFlat black finish for consistent appearance in modern architectural settings\u003c\/li\u003e\n\u003cli\u003eSold as a pair for a complete single-door installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style heavy-duty replacement or new-installation hinge for full-mortise door preparations with a 4 inches x 4 inches leaf size and 1\/4-inch radius corners.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a finish carpenter or door hardware installer.
