Overview

The Ningbo Dimon 3D Adjustable Concealed Door Hinge (180° Swing) is an architectural-grade invisible hinge engineered for modern minimalist flush doors, concealed doors, and high-end commercial or residential interior doorways. Completely recessed within the door slab and frame when closed, this hinge eliminates visible knuckles and exposed fasteners to deliver seamless, flush wall transitions. Featuring independent three-dimensional adjustability (vertical, horizontal, and depth), it allows installers to achieve flawless alignment and consistent door margins directly on site without removing the door leaf.

Key Features

• Full 180° Invisible Concealment: Completely hidden from view when the door is closed; swings open to a full 180° for an unobstructed passage and modern minimalist aesthetic.
• Independent 3D On-Site Adjustment: Easily calibrate door alignment with a standard hex key without unhanging the door leaf:
  • Vertical Adjustment: ±3 mm
  • Horizontal (Lateral) Adjustment: ±3 mm
  • Depth Adjustment: ±1.5 mm
• Heavy-Duty Load-Bearing Construction: Crafted with high-density die-cast zinc alloy bodies, heavy-duty stainless steel connecting linkages, and self-lubricating wear plates for silent, maintenance-free operation under 40 kg to 100+ kg loads.
• Concealed Snap-On Cover Plates: Sleek snap-in architectural covers conceal all adjustment screws and mounting fasteners for an immaculate, screwless finish.
• Non-Handed Reversible Design: Universal installation accommodates both left-hand and right-hand swinging doors, simplifying inventory and field installation.
• Architectural-Grade Finishes: Available in wear-resistant Matte Black and Satin Silver (Brushed Nickel) with superior corrosion and oxidation resistance.
