Built from steel with a primed gray finish, this hinge seats fully into routed mortises on both the door edge and the frame, leaving no exposed hinge barrel on the face of the door. It features a 4-inch overall width, 5 knuckles, 2 ball bearings for smooth operation, and a non-removable stainless steel pin for added security. Licensed contractors and door hardware installers specify this type of hinge for hollow metal and wood door assemblies in commercial builds.\u003c\/p\u003e\u003cp\u003eThis hinge is suited for full mortise installations in commercial, institutional, and light industrial door frames. The primed gray finish makes it ready to accept field-applied paint, which is standard practice on hollow metal door and frame assemblies. The non-removable pin design meets security requirements commonly called out in commercial door hardware schedules. It is appropriate for use on interior and exterior doors where a mortise hinge is specified per the project hardware set.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFull mortise mount type — seats flush into door edge and frame for a concealed appearance\u003c\/li\u003e\n\u003cli\u003eSteel hinge body with primed gray finish, ready for field painting\u003c\/li\u003e\n\u003cli\u003eStainless steel non-removable pin for enhanced security\u003c\/li\u003e\n\u003cli\u003e2 ball bearings for smooth, consistent swing operation\u003c\/li\u003e\n\u003cli\u003e5-knuckle design per Class 179FBB configuration\u003c\/li\u003e\n\u003cli\u003eMeets ANSI A8.1 and BHMA standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style full mortise replacement hinge for commercial hollow metal and wood door assemblies requiring a 4-inch leaf height and 4-inch overall width per ANSI A8.1 Class 179FBB specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a licensed door hardware installer or finish carpenter familiar with commercial door hardware schedules. Power down any electrified hardware tied to the door assembly before beginning work, and verify that mortise dimensions are routed to the correct depth before seating the hinge. Follow the applicable project hardware schedule and local building code requirements for fastener type and count. Do not force the hinge leaves into undersized mortises, as this can cause misalignment and binding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Full Mortise\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoor Leaf Height\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoor Leaf Width\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Leaf Height\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Leaf Width\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaf Thickness\u003c\/strong\u003e: 0.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHinge Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Non-Removable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Knuckles\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Ball Bearings\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Primed Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: 179FBB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI A8.1, BHMA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.88 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BEST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 711067282\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BEST","offers":[{"title":"Default Title","offer_id":51698504892722,"sku":"711067282","price":34.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2fad808b7f0afc1715bb2f9d88f6b983.jpg?v=1788363912","url":"https:\/\/voomisupply.com\/products\/best-711067282-full-mortise-concealed-hinge-steel-primed","provider":"Voomi Supply","version":"1.0","type":"link"}
