Spring hinges are self-closing door hardware components that use an internal coil mechanism to return a door to the closed position after each use. This hinge is sized for standard interior and light commercial doors and is installed by carpenters, finish contractors, and door hardware specialists. The zinc dichromate finish provides corrosion resistance suitable for dry interior environments. The unit ships individually and weighs 0.8 pounds.\u003c\/p\u003e\n\u003cp\u003eThis hinge is suited for residential and light commercial applications where a self-closing door function is required without the bulk of a hydraulic door closer. Typical installations include utility rooms, stairwell doors, and interior fire-rated door assemblies where self-closing hardware is specified by code. The 4-inch x 4-inch leaf size accommodates standard interior door thicknesses and frame widths common in residential and light commercial construction.\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-inch x 4-inch leaf dimensions fit standard interior door frames\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch corner radius for a traditional architectural profile\u003c\/li\u003e\n  \u003cli\u003eZinc dichromate plated finish offers corrosion resistance in dry interior conditions\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-unit or multi-unit purchase as needed\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 residential and light commercial interior doors requiring self-closing hardware.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSpring hinges are installed by carpenters or finish hardware contractors using standard door hinge installation techniques.
