The frame has a metallic angular profile (2) comprising a front surface (3) arranged parallel to a door opening and a bracket (4) at a frame outer side. A lower edge (11) of the angular profile comprises floor-sided distance (a) of more than 5mm, and the angular profile is attached at a foot angle (8). An arm (10) of the angular profile has step shape, and the angular profile is attached at a section (12) of the arm such that a gap with width of 2mm is formed between the lower edge and vertical surfaces of the foot angle, where the section is projected outward. |
