It uses a full mortise design, meaning the hinge leaf sits flush within a routed pocket in both the door edge and the door frame. The removable pin simplifies door hanging and removal without disturbing the leaf hardware. Heavy gauge steel construction adds load-bearing strength suited to everyday residential door traffic. This hinge ships one per pack and arrives carded for retail-style storage. Carpenters, finish contractors, and experienced DIYers are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis hinge is designed for residential interior and exterior door applications. Full mortise hinges are the standard choice for pre-hung and replacement door projects where a clean, flush appearance is required. The square corner profile matches traditional door frame routing patterns common in residential construction. The black finish suits doors and frames with matching dark hardware finishes. Each pack contains one hinge, so order quantity should match the number of individual hinges required for the job, typically two to three hinges per door leaf depending on door height and weight.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFull mortise design seats flush in routed door edge and frame pockets\u003c\/li\u003e\n  \u003cli\u003eRemovable pin for easier door installation and removal without disturbing mounted leaves\u003c\/li\u003e\n  \u003cli\u003eHeavy gauge material for added load strength on residential doors\u003c\/li\u003e\n  \u003cli\u003eNIB on hinge barrel for a finished, uniform appearance\u003c\/li\u003e\n  \u003cli\u003eSquare corner profile matches standard residential door routing\u003c\/li\u003e\n  \u003cli\u003eBlack finish for coordination with dark door and frame hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation full mortise hinge for standard residential interior and exterior doors requiring a 3-inch by 3-inch square corner leaf pattern.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by carpenters or finish contractors using a chisel and router to mortise the hinge leaf recesses into the door edge and frame jamb. Verify door and frame material thickness before routing to ensure proper leaf seating depth. Remove the pin before hanging the door to allow independent leaf placement, then reinsert once both leaves are aligned. Follow local building codes for hinge count and placement on exterior doors, particularly where fire-rated or security-rated assemblies are specified.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Size\u003c\/strong\u003e: 3 inches x 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Style\u003c\/strong\u003e: Square Corner\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHinge Type\u003c\/strong\u003e: Full Mortise\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Removable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential Interior and Exterior Doors\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 1 hinge per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.93 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: N241-182\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51560483946802,"sku":"N241-182","price":39.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5109efd2068c0e8cabbc0a010beb6d03.jpg?v=1786452914","url":"https:\/\/voomisupply.com\/products\/national-mfg-n241-182-3x3-black-square-corner-door-hinge","provider":"Voomi Supply","version":"1.0","type":"link"}
