Measuring 3 inches x 3 inches with a square corner profile, this heavy-gauge hinge is built to handle industrial, commercial, and residential door applications. The stainless steel construction provides maximum protection against rust and corrosion, making it especially well-suited for marine settings and other outdoor exposures. A non-rising, removable pin simplifies installation and hinge alignment. A NIB on the bottom of the hinge leaf delivers a clean, finished appearance once installed.\u003c\/p\u003e\u003cp\u003eThis hinge is intended for use on doors in environments subject to moisture, salt air, or other corrosive conditions. It is appropriate for marine vessel doors, coastal residential entry doors, commercial exterior doors, and industrial facility doors where standard steel hardware would degrade prematurely. Each pack contains 3 hinges, sold per pack. Installation is performed by carpenters, millworkers, or general contractors working on door hanging in mortise-style applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStainless steel construction for maximum corrosion resistance in marine and outdoor applications\u003c\/li\u003e\n\u003cli\u003eFull mortise design for flush, recessed installation\u003c\/li\u003e\n\u003cli\u003eSquare corner profile for standard door frame compatibility\u003c\/li\u003e\n\u003cli\u003eNon-rising pin prevents hinge from riding up during door operation\u003c\/li\u003e\n\u003cli\u003eRemovable pin for easier door hanging and hinge alignment\u003c\/li\u003e\n\u003cli\u003eHeavy-gauge material provides added strength and long-term durability\u003c\/li\u003e\n\u003cli\u003eNIB on bottom leaf for a finished, professional appearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation hinge for full-mortise door applications in industrial, commercial, and residential settings, particularly where corrosion resistance is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is a full-mortise application requiring a chisel or router to cut hinge mortises into both the door edge and the door frame jamb.
