Manufactured from cold rolled steel, it features a five-knuckle design and a swaged construction that ensures precise alignment in mortise applications. The loose pin design allows a door to be removed from its frame without uninstalling the hinge leaves, which saves time during service calls and remodeling work. At 3 inches, this hinge suits standard interior and light-duty commercial door applications. It is installed by carpenters, general contractors, and finish tradespeople working on residential or light commercial projects.\u003c\/p\u003e\n\u003cp\u003eThis hinge is suited for full mortise door installations where the hinge leaf is recessed flush into both the door edge and the door frame. The loose removable pin design is particularly useful in high-traffic areas or wherever doors may need to be temporarily removed for clearance during construction or renovation. Each package contains 10 hinges, making it practical for multi-door projects or service stock. The plain steel finish is appropriate for applications where the hinge will be painted over or where a primed surface is acceptable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRemovable loose pin allows door removal without uninstalling hinge leaves\u003c\/li\u003e\n  \u003cli\u003eFull mortise design with swaged leaves for flush, precise installation\u003c\/li\u003e\n  \u003cli\u003eFive-knuckle construction for added strength and smooth operation\u003c\/li\u003e\n  \u003cli\u003eCold rolled steel material provides consistent hardness and surface quality\u003c\/li\u003e\n  \u003cli\u003e3-inch leaf size suits standard residential and light commercial doors\u003c\/li\u003e\n  \u003cli\u003ePackaged loose in a box, 10 units per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for full mortise door applications requiring a 3-inch broad hinge with a removable pin.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by carpenters or finish tradespeople using standard wood chisels, a mallet, and a drill or screwdriver. Power down any electric strikes or access control hardware connected to the door before removing or reinstalling the door panel. Mortise the hinge recess to the correct depth so the leaf sits flush with the door edge and frame face. Verify the pin is fully seated after hanging the door to prevent unintended removal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHinge Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cold rolled steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnuckle Count\u003c\/strong\u003e: Five knuckle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Removable loose pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Type\u003c\/strong\u003e: Full mortise\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.8 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NATIONAL MFG\/SPECTRUM BRANDS HHI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N139-808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51558711853362,"sku":"N139-808","price":46.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf6dc229ceefdd5a11005fccf6255e54.jpg?v=1786418678","url":"https:\/\/voomisupply.com\/products\/national-mfg-n139-808-3-inch-steel-removable-pin-broad-hinge","provider":"Voomi Supply","version":"1.0","type":"link"}
