The profile (10) has an anchor foot (20) that engages an undercut receiving groove (80) of a profile (90). A transition section (30) is provided adjacent to the anchor foot. A base section (40) is provided adjacent to the transition section. A closed cavity extends into the anchor foot and into the transition section and comprises two cavity sections (52, 54), where the constant clearance (G) of one of the cavity sections (54) is lesser than the constant clearance (H) of the other cavity section. |
