Designed with an ultra-narrow 18 mm leaf width, this concealed hinge requires significantly shallower mortise pockets, making it ideal for narrow door stiles and minimalist architectural jambs. With full 3-axis adjustment, unhanded non-directional installation, and durable all-metal zinc alloy construction, it delivers seamless flush closure and smooth, whisper-quiet 180-degree door swing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUltra-Narrow 18 mm Leaf Profile:\u003c\/strong\u003e Extremely slim 18 mm width minimizes router mortising depth and fits narrow-stile doors, slim aluminum profiles, and concealed secret panel installations without compromising structural integrity.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision 3D Adjustment:\u003c\/strong\u003e Independent micro-adjustments in three dimensions (vertical ±1.5mm, horizontal ±1.5mm, depth ±1.0mm) allow precise door alignment after hanging, eliminating gaps and binding.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniversal Non-Handed Design:\u003c\/strong\u003e Completely reversible geometry operates identically on left-hand and right-hand inward or outward swinging doors.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmooth 180° Full-Swing Pivot:\u003c\/strong\u003e Multi-link pivot arm mechanism opens up to 180 degrees, providing unobstructed clear walk-through passage and concealed flush seating when closed.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeavy Load Capacity:\u003c\/strong\u003e Premium solid zinc alloy body with high-tensile steel pivot pins supports up to 40 kg (88 lbs) per pair (or up to 60 kg with 3 hinges).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConcealed Screw Cover Plates:\u003c\/strong\u003e Sleek snap-on magnetic or set-screw covers completely conceal mounting screws for an immaculate, seamless architectural finish.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Ultra-Thin 3D Adjustable Concealed Invisible Door Hinge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-Density Zinc Alloy Body, Structural Steel Linkages \u0026amp; Pivot Pins\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Width:\u003c\/strong\u003e 18 mm (Ultra-Slim Narrow Profile)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpening Angle:\u003c\/strong\u003e 180 Degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDoor Handing:\u003c\/strong\u003e Non-Handed (Universal for Left \u0026amp; Right hand doors)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3D Adjustment Range:\u003c\/strong\u003e\n    \u003cul\u003e\n      \u003cli\u003e\n\u003cem\u003eVertical (Up\/Down):\u003c\/em\u003e ±1.5 mm\u003c\/li\u003e\n      \u003cli\u003e\n\u003cem\u003eHorizontal (Left\/Right):\u003c\/em\u003e ±1.5 mm\u003c\/li\u003e\n      \u003cli\u003e\n\u003cem\u003eDepth (In\/Out):\u003c\/em\u003e ±1.0 mm\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad Rating:\u003c\/strong\u003e 40 kg (88 lbs) per 2 hinges \/ 60 kg (132 lbs) per 3 hinges\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable Finishes:\u003c\/strong\u003e Architectural Matte Black, Satin Silver \/ Brushed Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications:\u003c\/strong\u003e Concealed flush interior doors, hidden bookcase doors, wardrobe panels, secret doors, and minimalist architectural millwork\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWholesale \u0026amp; OEM Capabilities\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFactory-Direct Supply:\u003c\/strong\u003e Manufactured by Ningbo Dimon for door manufacturers, custom cabinet shops, architectural millwork contractors, and hardware importers.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOEM Customization:\u003c\/strong\u003e Custom surface plating\/finishes (Matte Black, Brushed Brass, Gunmetal, Satin Nickel), bespoke router milling templates, and private-label packaging.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExport Packaging:\u003c\/strong\u003e Packed in pairs with protective inner blister trays, complete hex adjustment keys, and stainless steel wood screws in heavy-duty master cartons.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ningbo Dimon Metal Products Co.,Ltd","offers":[{"title":"Black","offer_id":47111120846987,"sku":null,"price":110.0,"currency_code":"USD","in_stock":true},{"title":"Silver","offer_id":47111120879755,"sku":null,"price":110.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0575\/0295\/7707\/files\/ba1c327e56cafd6493802901e67f847a.jpg?v=1790137646","url":"https:\/\/nbdimon.myshopify.com\/ar\/products\/ultra-thin-invisible-door-hinge","provider":"Ningbo Dimon Metal Products Co.,Ltd","version":"1.0","type":"link"}
