Part of the National catalog V504 through V504BC series, this hinge features a removable loose pin that allows doors to be lifted free without removing the hinge from the frame. The body is galvanized steel with a brass pin, providing corrosion resistance suited to light industrial and commercial environments. It is swaged for mortise installations, making it compatible with standard door framing practices used by carpenters, millwrights, and maintenance professionals.\u003c\/p\u003e\u003cp\u003eThis hinge is suited for residential, commercial, and light industrial door installations where mortise-style mounting is required. The swaged design fits cleanly into routed mortise pockets on door edges and frames, delivering a flush, professional finish. The loose pin configuration is particularly useful in high-traffic service environments where doors may need to be removed frequently without disturbing the mounted leaves. It is sold individually, with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRemovable loose pin allows door removal without uninstalling the hinge leaves\u003c\/li\u003e\n\u003cli\u003eSwaged construction designed for mortise installations\u003c\/li\u003e\n\u003cli\u003eGalvanized steel body with brass pin for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e2.5-inch square profile fits standard utility and industrial door applications\u003c\/li\u003e\n\u003cli\u003ePart of the National V504 through V504BC catalog series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use hinge for mortise-style door installations in residential, commercial, and light industrial settings.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by carpenters, maintenance technicians, or millwrights using standard chisels and screwdrivers for mortise preparation and fastening.
