What is a Wide-Angle Hinge? Function for Corner Cabinets & Internal Drawers
A wide-angle hinge is a specialised concealed hinge that enables an above-average opening angle of typically 155° or 165°. It swings the cabinet door completely clear of the internal carcass opening. This is strictly required for corner cabinets with carousel systems as well as for units fitted with internal drawers.
What exactly is a wide-angle hinge?
While standard furniture door fittings generally feature an opening angle of 95° to 110° – which is sufficient for regular shelves – they reach their limits with specialised internal fittings. A classic concealed hinge for 110 degrees leaves the open edge of the door protruding slightly into the interior space of the cabinet.
A wide-angle hinge uses complex multi-joint kinematics. It operates like a multi-jointed robot arm that does not merely rotate the door around one axis when opening, but simultaneously pushes it sideways in front of the cabinet side panel. This creates the so-called zero protrusion. The opened door no longer intrudes into the clear internal width of the cabinet, making the entire interior fully and easily accessible.
Typical dimensions and standards
In furniture construction, wide-opening hinges also adhere to standardised dimensions to ensure compatibility with standard drilling patterns such as System 32.
- Cup diameter: The standard drilling for the hinge cup is 35 mm. Corresponding concealed hinges with 35 mm are the industry norm.
- Drilling depth: The cup usually requires a routing depth of 11.5 mm to 13 mm.
- Opening angle: The most common variants are concealed hinges for 155 degrees as well as models designed for maximum accessibility, rated as concealed hinges for 165 degrees.
- Closing mechanism: Modern versions are frequently constructed as concealed hinges with soft-close. The integrated closing mechanism slows the door down over the last few centimetres and pulls it shut silently (Soft-Close).
Application and selection: Corner cabinets & internal drawers
The choice of a wide-angle hinge is dictated by the internal layout of the cabinet carcass. Two scenarios make this hardware essential for installers:
1. Cabinets with internal pull-outs
When drawers are mounted behind a full-length cabinet door, they must glide past the opened door when pulled out. Without the zero protrusion of a wide-angle hinge, the drawer front would collide with the door.
2. L-shaped kitchens and corner solutions
In corner cabinets equipped with a corner cabinet carousel fitting or swing-out shelves, the door must be able to open extremely wide so that the internal mechanism can extend without obstruction. In bi-fold door combinations, the wide-angle hinge connects the first door to the carcass, while a separate corner hinge connects the two door leaves to one another.
Mounting types for wide-angle hinges
As with standard hinges, the position of the door relative to the carcass must be considered. Choosing the correct cranked version determines the door alignment and gap pattern:
- Full overlay: The door lies completely over the carcass side edge. For this, concealed hinges for full overlay (straight/uncranked) are used.
- Half overlay: Two doors share a single central divider panel. The hinge is half-cranked. Concealed hinges for half overlay are suitable here.
- Inset: The door sits flush inside the carcass sides. Highly cranked concealed hinges for inset applications are used in this case.

- Cross mounting plate: The counterpart on the carcass onto which the wide-angle hinge clips and is adjusted across three dimensions (height, depth, and gap).
- Zero protrusion: The property of a hinge swinging the door completely out of the pull-out path.
