natura 4000 handles

The right handle for each door-system: swing and pivot doors are integrated harmoniously into the profile - beautiful and easy to clean at the same time.

For an easy use of the bi-folding door, the handle has been attached horizontally on the glass.

Technical details

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

The corner entry model presents itself with a special connection of the horizontal profiles, which stresses subtly the modernity of the model.

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

The ball bearing mounted and in their height adjustable rollers in the guide rail ensure a supreme gliding comfort of the doors.

The closed inner side of the guide rail combines an appealing optical appearance with an easy cleaning.

The lower guide system conceals a typical Duka-innovation: through the magnetic support the door glides sturdily and calmly on a guiding hook, which can be unlocked in order to clean the door.
