<p>The sealing element (10) has beams (11, 12) connected with outer and inner frames, respectively at a front side of an upright profile, where the frames are relevant to the upright profile. A bridge section (13) connects the beams, and fixes a distance between the beams, where length of the bridge section and the distance between the beams are variably adjusted. The bridge section has base sections (14, 15) firmly connected with the respective beams. The base sections telescopically interact with each other so that the length of the bridge section is variably adjusted.</p> |
