Measuring 3.5 inches by 3.5 inches with a 0.25-inch throw, it provides consistent return tension to close a door automatically after each pass. The hinge is finished in Bright Brass by Satin Brass, offering a two-tone aesthetic suited to traditional and transitional door hardware schemes. Constructed from solid brass, it resists corrosion and holds up under repeated cycling. This type of spring hinge is a standard component specified by door hardware installers, finish carpenters, and general contractors on projects requiring code-compliant self-closing doors.\u003c\/p\u003e\n\u003cp\u003eThe DSH35R43\/4 is suited for interior doors in residential homes, apartment units, light commercial offices, and institutional corridors where self-closing function is required by building code or owner specification. Typical applications include fire-rated door assemblies where a self-closing device is mandated, as well as entry doors to utility rooms, mechanical spaces, and child-safe areas. It is sold individually and packaged in case quantities of 50 units, making it practical for both single-door service calls and larger new-construction or renovation projects.\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\u003e3.5 inches x 3.5 inches leaf size fits standard residential and light commercial door frames\u003c\/li\u003e\n  \u003cli\u003e0.25-inch throw accommodates typical door edge profiles\u003c\/li\u003e\n  \u003cli\u003eSolid brass construction for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eBright Brass by Satin Brass two-tone finish for architectural compatibility\u003c\/li\u003e\n  \u003cli\u003eSold individually; available in case quantities of 50\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 3.5-inch door hinge preps on residential and light commercial door frames.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSpring hinges of this type are installed by finish carpenters, door hardware specialists, or general contractors following the door manufacturer's hinge prep specifications.
