<p>In a building with heavy hanging doors or partitions, the moving components slide on a rail (1) that is attached to the overhead hardened structure by a bolt (8) and plug (7) located in an elongated profile (3). The profile is embedded within the wall (6) and has an arched top profile (312) with side-shoulders extending into the adjacent structure. The profile is fitted during building construction without the rail. The rail is subsequently installed.</p> |
