It measures 4.5 inches by 4.5 inches and is designed to provide controlled, self-closing door operation in commercial and light commercial door assemblies. The spring mechanism applies consistent return force to keep doors closed without a separate door closer, making it a practical choice for interior doors where code-required self-closing hardware is needed. At 1.25 pounds, the hinge offers solid construction suited to standard mortise door prep. Installation is typically handled by carpenters, door hardware specialists, or commercial contractors.\u003c\/p\u003e\u003cp\u003eThis spring hinge is intended for full mortise door applications where a square corner leaf profile is required. It is well suited to interior passage doors, corridor doors, and similar single-door assemblies in light commercial, institutional, or residential settings. The satin chrome finish blends with contemporary hardware trim packages. The single acting design allows the door to swing in one direction only, returning to the closed position after each use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFull mortise mounting — fits standard mortise door and frame preparation\u003c\/li\u003e\n\u003cli\u003eSingle acting spring mechanism provides consistent self-closing force\u003c\/li\u003e\n\u003cli\u003eSquare corner leaf profile for clean, flush installation\u003c\/li\u003e\n\u003cli\u003e4.5 x 4.5 inch leaf size accommodates standard commercial door thickness\u003c\/li\u003e\n\u003cli\u003eSatin chrome finish for corrosion resistance and contemporary appearance\u003c\/li\u003e\n\u003cli\u003eSold individually — one hinge per unit\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 full mortise, square corner door preparations in standard commercial and residential door assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified carpenters or door hardware technicians familiar with mortise hinge prep.
