Spring hinges are self-closing hinges used on doors that must return to a closed position without a separate door closer. The spring mechanism is built into the barrel and provides consistent closing tension. This hinge is manufactured from solid brass and is sold as a single unit. It is a standard architectural hardware component installed by carpenters, finish contractors, and door hardware technicians on residential and light commercial doors.\u003c\/p\u003e\n\u003cp\u003eThis spring hinge is suited for interior door applications where a self-closing function is required, such as fire-rated corridor doors, stairwell access doors, and utility room entries. The oil rubbed bronze finish coordinates with matching lever sets, door stops, and other architectural hardware. The radius corner profile matches standard door hinge mortise cutouts common on pre-hung door assemblies, simplifying retrofit and replacement installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSelf-closing spring mechanism built into the hinge barrel for reliable door return\u003c\/li\u003e\n  \u003cli\u003e4 inch x 4 inch leaf size fits standard full-mortise hinge prep on residential and light commercial doors\u003c\/li\u003e\n  \u003cli\u003eRadius corner design matches common pre-hung door mortise profiles\u003c\/li\u003e\n  \u003cli\u003eOil rubbed bronze finish for coordination with architectural hardware sets\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit — order quantity matches project needs\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 full-mortise door applications requiring a 4 inch x 4 inch hinge with radius corners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSpring hinges are installed by carpenters or door hardware technicians using standard mortise chisels, a drill, and a screwdriver or bit driver. Power down any electric strike or access control hardware associated with the door before beginning work.
