Emtek 91023US19 Steel Door Hinge Pair 3.5in Flat Black

Product Description

The EMTEK 91023US19 is a pair of residential-duty steel door hinges finished in flat black. 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.

These 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.
