Spring hinges are self-closing door hardware components that use an internal coil spring mechanism to return a door to its closed position without a separate door closer. This hinge measures 5.5 inches in length, 3 inches in width, and 1 inch in depth, and weighs 0.84 pounds. It is installed by carpenters, millwork contractors, and door hardware specialists in both residential and light commercial applications where code-required self-closing doors are specified.\u003c\/p\u003e\u003cp\u003eThis spring hinge is suited for interior door installations where self-closing function is required, such as fire-rated corridor doors, stair access doors, and utility room entries in residential and commercial construction. The left-hand designation applies to doors where the hinge barrel must be oriented to the left when viewed from the pull side. The paint black finish integrates cleanly with painted door and frame assemblies without visible hardware contrast. It is sold individually and is available in case quantities of 50 units for larger projects.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSelf-closing spring mechanism eliminates need for a separate surface-mounted door closer\u003c\/li\u003e\n\u003cli\u003eLeft-hand orientation for correct barrel alignment on LH door applications\u003c\/li\u003e\n\u003cli\u003e4 inches x 4 inches leaf size with 5\/8 inch radius and square corner profile\u003c\/li\u003e\n\u003cli\u003ePaint black finish suited for painted hollow-metal or wood door assemblies\u003c\/li\u003e\n\u003cli\u003eCompact 1 inch depth keeps the profile tight to the door edge\u003c\/li\u003e\n\u003cli\u003eSold individually with case quantity of 50 units available\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation spring hinge for standard 4 inches x 4 inches hinge prep doors requiring a left-hand, self-closing function in residential or light commercial applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSpring hinges are installed by qualified carpenters or door hardware technicians familiar with door prep and hinge mortising requirements.
