Overview

The Ningbo Dimon Concealed Top & Bottom Pivot Hinge is an architectural-grade concealed pivoting system designed specifically for narrow-profile aluminum frame glass doors, luxury display cases, modern wardrobes, and wine cabinet cabinetry. By installing directly into the top and bottom header and floor of the cabinet carcass—rather than mounting on the side panels—it achieves a completely seamless, minimalist aesthetic with zero visible hardware on the cabinet exterior. Integrated with an internal hydraulic buffer damper, this pivot hinge provides silky-smooth, silent soft-closing performance, eliminating door slamming and protecting delicate tempered glass inserts.

Key Features

• Top & Bottom Vertical Pivot Mount: Conceals the entire hinge body inside the cabinet top panel, bottom panel, and aluminum corner profile, keeping cabinet sidewalls clean and unmarred.
• Built-In Hydraulic Soft-Close Damper: High-performance hydraulic piston buffer gently catches the door leaf in the final closing degrees, providing whisper-quiet, cushioned closing.
• Independent 3D Precision Adjustability: Allows effortless post-installation alignment using a standard screwdriver:
  • Left / Right Lateral Adjustment: ±2.0 mm
  • Up / Down Height Adjustment: ±1.5 mm
  • Front / Back Depth Adjustment: +2.0 mm / -0.5 mm
• Heavy-Duty 35kg (77 lbs) Capacity: Engineered from high-density zinc alloy and cold-rolled steel to support tall, full-height aluminum framed glass panels up to 35 kg per pair.
• Seamless Aluminum Frame Integration: Includes dedicated 45° miter corner bracket connectors that slide directly into standard aluminum extrusion slots for rigid, square door assembly.
• Wide Range of Door Dimensions: Accommodates door thicknesses from 13 mm to 32 mm, ideal for slim-profile modern glass vitrines and wardrobe systems.
