The opening angle increases gradually between 0 and 45 degrees. The upper pivot hinge is available optionally with or without cable passage.

System 3 offers a 360° rotational movement along with features such as self-closing and locking positions. From any 45° angle, System 3 automatically swings into the locking positions of 0°, 90°, 180°, or 270°. The 360° rotation combined with the locking positions and the automatic closing function are ideal characteristics for movable walls.

The maximum door height depends on the door material and maximum door weight. The doors have been tested for 1,000,000 door cycles.
