The closure i.e. glass door (1), has a metallic profile divided into partial profiles (3, 4) in an area of front surfaces of a fire protection disk (2). The partial profiles overlap side surfaces (9) of the protection disk, where front surfaces of the disk are connected with the side surfaces. The partial profiles are arranged at a distance to each other and provided with two side pieces (6, 7). A bar (8) is fixed parallel to one of the side pieces and attached to the front surfaces of the disk. The partial profiles are made of a single-piece metal strip that is made of stainless steel. |
