Spring hinges are self-closing door hardware designed to return a door to a closed position without a separate closer mechanism. This hinge is built for interior door applications where code-compliant self-closing function is required, such as fire-rated corridor doors or utility room entries. It measures 5.25 inches in length, 2.8 inches in width, and 0.9 inches in height, and weighs approximately 0.8 pounds per unit.\u003c\/p\u003e\n\u003cp\u003eThis spring hinge is suited for residential and light commercial door installations where a self-closing hinge is needed to meet fire code or building code requirements. The mixed corner profile — radius on one leaf, square on the other — accommodates door frames and slabs that use different corner styles, providing installation flexibility. It is sold as a single unit and is appropriate for standard interior door applications handled by carpenters, door hardware installers, or general contractors.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSelf-closing spring mechanism returns door to closed position without a separate closer\u003c\/li\u003e\n  \u003cli\u003e4 inches x 4 inches hinge size suits standard interior door applications\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch radius on one leaf, square corner on the other for mixed-frame compatibility\u003c\/li\u003e\n  \u003cli\u003eZinc dichromate plated finish provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 5.25 inches length x 2.8 inches width x 0.9 inches height\u003c\/li\u003e\n  \u003cli\u003eSold individually for single-door or multi-hinge configuration flexibility\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, typically used where a 4-inch x 4-inch hinge footprint is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSpring hinges are installed by carpenters or door hardware professionals and require standard hinge mortising tools. The spring tension is adjustable after installation using the provided tension pin — follow the manufacturer's instructions and do not over-tension the spring.
