The unit consists of a supporting bracket (6) fixed to a straight strip (3) welded to the outer surface of a vertical supporting tube (2) parallel to its axis. The bracket has a concave recess (5) fitting into a cavity in the strip and shaped to receive the supported horizontal tube (1), which is held in place by a curved outer collar (11) with its upper and lower edges (12,13) welded to the bracket. The lower (7) and upper (8) ends have slots to fit over the strip and are welded to it. |
