Within Door 2000, Do:Dia and Lualdi collections there is always a possibility to combine the door leaf with different types of frames. On the picture you can see samples of following frames (left to right):

Picture A: Hidden ALU frame
Picture B: Hidden Taeda frame

Picture D: Telescopic Taeda frame

Within Door 2000 (Collection 2000, Maree and Planet) it is also possible to have the classic telescopic frame in soft curved version – Rondo/Spazio.
