Technical details

The intelligent hinge of the bi-folding door with a 180° opening, is equipped with an AC-mechanism.

The turning technology of the doors contains an innovative AC-system and provides an autonomous closing of the door on the last centimetres.

The hinge now takes on a new, more fluid form in harmony with the soft lines of the model. This element, with its minimal and light design, retains its intrinsic functionality, but now does so with amplified beauty. The hinge allows a 180° outward opening.

The folding/pivoting hinge is bonded to the glass using innovative Duka UV glueing technology. This means that neither drill holes nor cut-outs are required. What remains is a pristine glass surface with a clean appearance for easier cleaning.

The cylindrical tubular hinge has been reduced to a minimum, allowing the transparency of the glass to take centre stage. Minimalistic in appearance, great in functionality: the proven "auto close" closing system allows the pivot elements to engage exactly where required.

With several solutions, the door can be adjusted to the millimetre using an adjustment wheel - even years later. multi-S 4000: well thought-out from installation to application.
