Designed for heavy-duty door applications, it features a 3-knuckle design and a 360-degree range of motion, providing full rotational clearance for standard and specialized door swings. The door leaf and frame leaf each measure 4.5 inches in height and 2 inches in width. Weighing 1.2 pounds, this hinge is built for durable, long-term performance in commercial environments. It is installed by carpenters, door hardware specialists, and commercial contractors as part of new construction or retrofit projects.\u003c\/p\u003e\n\u003cp\u003eThis hinge is suited for commercial door installations involving wood and metal door types. Its full mortise design requires routing into both the door edge and frame, making it a clean, flush-mount solution. It meets ANSI K81071F and NFPA 80 standards, making it appropriate for fire-rated door assemblies and commercial code-compliant installations where these standards apply. The prime coat grey finish allows for field painting to match existing hardware or door frame finishes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFull mortise mount type for flush installation in door edge and frame\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in commercial applications\u003c\/li\u003e\n  \u003cli\u003e3-knuckle design with 360-degree range of motion\u003c\/li\u003e\n  \u003cli\u003ePrime coat grey finish suitable for field painting\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI K81071F and NFPA 80 standards for fire-rated door assemblies\u003c\/li\u003e\n  \u003cli\u003eCompatible with wood and metal door types\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style full mortise replacement hinge for commercial wood and metal doors requiring ANSI K81071F and NFPA 80 compliant hardware.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFull mortise hinges are installed by qualified door hardware technicians or commercial contractors.
