Each hinge measures 3.5 inches by 3.5 inches with a 0.25-inch corner radius, providing a clean, squared appearance suited to modern and transitional interior door applications. Constructed from steel, these hinges offer reliable load-bearing performance for standard residential passage doors. Supplied as a pair, they are installed by carpenters, finish trim contractors, and general contractors during door hanging or hardware replacement. The flat black finish delivers a consistent, low-sheen appearance that coordinates with contemporary door hardware sets.\u003c\/p\u003e\n\u003cp\u003eThese hinges are intended for residential interior door installations where a 3.5-inch by 3.5-inch hinge is the specified size. The 0.25-inch radius corner profile is a widely used standard that fits pre-mortised door frames and door blanks prepared for that corner geometry. Sold as a pair, one order supplies hardware for a single door location. They are well-suited for bedroom, closet, and hallway passage doors in new construction and remodel projects. The flat black finish is consistent with EMTEK door hardware families offered in matching black finishes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eResidential duty steel construction for standard interior door applications\u003c\/li\u003e\n  \u003cli\u003e3.5 inches x 3.5 inches hinge leaf size with 0.25-inch radius corners\u003c\/li\u003e\n  \u003cli\u003eFlat black finish for a clean, low-sheen appearance\u003c\/li\u003e\n  \u003cli\u003eSold as a matched pair for single-door installation\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard pre-mortised door frames and door blanks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style residential replacement or new-installation hinge for standard interior doors mortised for a 3.5-inch by 3.5-inch hinge with a 0.25-inch corner radius.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed carpenter or finish contractor using a chisel, mallet, and drill.
