Introduction

Today, we’ll be discussing the hinges that allow for a practical and functional installation of flap-opening doors.
Wall cabinets, small wardrobes, pantries, bedside tables, bathroom and kitchen cabinets… There are countless opportunities to replace traditional side-opening doors with flap-opening ones, which offer a modern and versatile alternative.

Opening Mechanisms for Flap Doors

First of all, it’s worth noting that flap doors can open either upwards or downwards. In some cases, it might be useful to install a double door on a cabinet—one that opens upwards and another that opens downwards.
This way, the lower door, once opened, can provide a convenient surface to use as a shelf, without protruding excessively from the piece of furniture itself.

Huwil Duo Häfele Hinges

n this article, we focus specifically on the Huwil Duo Häfele hinge, the most classic choice for flap-opening mechanisms. Its simplicity lies in its adaptability, as it suits almost all types of household furniture. A single support can hold up to 11 kg, and it offers reversible usage, meaning it can be mounted on either the right or left side. It is secured using brackets, which it clips onto via a pressure mechanism.

Types of Flap Doors You Can Mount

The Huwil Duo Häfele hinge can be used, simply by reversing the position of the levers, both as a support for flap doors that open upwards and as a stopper for flap doors that open downwards.

Installation Methods for Downward-Opening Flap Doors

When used for downward-opening flap doors, the hinge can be mounted, as shown in the diagram, in two different positions. In the second mounting method described, the rod does not require the additional retaining element.

Installation Methods for Upward-Opening Flap Doors

When used for upward-opening flap doors, there is the option to achieve a door opening angle of 75°, 90°, or 110°, depending on how the supports are mounted (and, naturally, which hinges are used).
Additionally, a VIDEO INSTRUCTION GUIDE FOR INSTALLATION is available, providing clear steps to follow during assembly to make the most of the various options offered by the hinge.

Huwil Maxi Häfele Hinges

Another category of hinges worth highlighting is the Huwil Maxi Häfele model. This innovative system for flap doors is highly versatile, as it can be applied to cabinets with or without handles for opening, even for large doors weighing up to 50 kg.
The complete Maxi set available on Tuttoferramenta encompasses all models in the range, with distinctions based on the weight they support. The fractional adjustment depends on the door’s weight, and you’ll find color-coded rings corresponding to increasing weights:

A = Grey ring
B = Beige ring
C = White ring
D = Black ring

The Huwil Maxi system features a variable opening angle that can be set at 75°, 90°, or 110°, and it can be complemented with a damper for smoother door movement.
A VIDEO INSTRUCTION GUIDE FOR INSTALLATION is also available, providing detailed steps for mounting and adjusting the hinges.
