For swing doors, the upper and lower pivot hinge is invisibly milled into the door. It features maintenance-free moving parts and is suitable for doors with a thickness of 40 mm or more. The hinge can be retrofitted as no structural modifications are required. It is also compatible with underfloor heating. All functions and adjustment options are integrated into the hinge. From an opening angle of approximately 45 degrees, the door automatically continues to rotate to the 90-degree position. The opening angle gradually increases between 0 and 45 degrees. The upper pivot hinge is available optionally with or without cable routing.

System 3 offers a 360° rotational movement along with features such as self-closing and fixed stop positions. From any 45° angle, System 3 automatically swings into the fixed stop positions of 0°, 90°, 180°, or 270°.

The 360° rotation combined with the fixed stop 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.
