Built from heavy-gauge stainless steel, it delivers strong corrosion resistance in demanding environments including coastal, industrial, and high-moisture applications. The 5-knuckle design provides smooth, stable pivot action, while the non-rising pin keeps the hinge seated through repeated use. Countersunk screw holes allow fasteners to sit flush, and the removable pin simplifies installation and door removal. A decorative knob on the hinge gives it a finished appearance suited to visible door applications.\u003c\/p\u003e\n\u003cp\u003eThis hinge is appropriate for residential and light commercial door installations where corrosion resistance and a clean aesthetic are both required. The full mortise configuration means it recesses flush into the door edge and frame, which is standard for most interior and exterior door framing applications. It is installed by carpenters, general contractors, and maintenance trades working on entry doors, passage doors, or utility enclosures that see moisture exposure. This part corresponds to National catalog model V514.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeavy-gauge stainless steel construction for maximum corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e5-knuckle, full mortise design for flush, stable installation\u003c\/li\u003e\n  \u003cli\u003eNon-rising pin maintains consistent hinge position under load\u003c\/li\u003e\n  \u003cli\u003eRemovable pin for easier door hanging and removal\u003c\/li\u003e\n  \u003cli\u003eCountersunk screw holes for flush fastener seating\u003c\/li\u003e\n  \u003cli\u003eDecorative knob provides a finished appearance on visible installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install hinge for standard full mortise door applications requiring a 4-inch square stainless steel hinge.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall by qualified carpenters or maintenance personnel familiar with door hardware. Power down any electronic door hardware or access control systems before servicing the door assembly.
