Spring hinges are self-closing door hardware components that use an internal coil spring mechanism to return a door to its closed position after opening. This hinge is built for interior door installations where code or design requirements call for a self-closing function. It is typically installed by carpenters, finish contractors, or licensed door hardware specialists working on residential and light commercial projects. The paint black finish provides a consistent, matte appearance suited to modern and transitional door designs.\u003c\/p\u003e\n\u003cp\u003eThis spring hinge is appropriate for interior passage doors, fire-rated door assemblies requiring self-closing hardware, and similar applications where automatic door return is required. The 4.5 x 4.5 inch leaf size accommodates standard interior door weights and thicknesses common in residential and light commercial construction. It is sold individually, making it practical for single-door replacement or targeted repair work without purchasing a full set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSelf-closing spring mechanism returns door to closed position automatically\u003c\/li\u003e\n  \u003cli\u003e4.5 x 4.5 inch leaf size for standard interior door applications\u003c\/li\u003e\n  \u003cli\u003ePaint black finish for a clean, matte appearance\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit for flexible replacement purchasing\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 5.5 x 2.9 x 0.9 inches packaged dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation spring hinge for standard interior doors requiring self-closing hardware with a 4.5 x 4.5 inch hinge leaf format.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSpring hinges are installed by carpenters or door hardware contractors and typically replace standard butt hinges in the existing mortise.
