Constructed from galvanized steel with a brass pin, this hinge is swaged for mortise-style installations, providing a clean fit in routed door and frame pockets. The loose removable pin design allows doors to be pulled off the frame without uninstalling the hinge leaves, which saves time during service, equipment access, or renovation work. Licensed tradespeople and facilities maintenance technicians install this type of hardware on interior and exterior doors in industrial, commercial, and general utility settings.\u003c\/p\u003e\n\u003cp\u003eThis hinge suits residential and light industrial door installations where a mortise-mount broad hinge is required. The galvanized finish provides corrosion resistance suitable for humid or moderately exposed environments. The removable brass pin makes this a practical choice on access panels, utility room doors, and equipment enclosures where doors need to be removed periodically without disturbing the mounted hinge leaves. It is sold individually and rated for standard door weight loads appropriate to its 3-inch square leaf size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch square leaf profile sized for standard utility and industrial door applications\u003c\/li\u003e\n  \u003cli\u003eLoose removable brass pin allows door removal without uninstalling hinge leaves\u003c\/li\u003e\n  \u003cli\u003eSwaged leaves designed for mortise installation in door and frame\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel construction provides corrosion resistance in humid environments\u003c\/li\u003e\n  \u003cli\u003eBrass pin resists galling and allows smooth pin withdrawal during removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis hinge is part of the National catalog V504 through V504BC series and is designed as an OEM-style replacement or new-install broad door hinge for general utility and industrial mortise door applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by carpenters, millwrights, or facilities maintenance technicians. Power down or de-energize any electrically controlled door hardware before beginning work. Mortise the door and frame to the exact leaf dimensions before seating the hinge to ensure a flush fit.
