Searched & Searched till I found a unit that could hold the weight of a nearly 12' "curtain divider wall" in a basement.  This item did it well a 5* rod..  It was easy to assemble. It goes onto wall (but perhaps could do ceiling too, in my estimation) and is sturdy at 25lb to 30 lb weight.  I installed brackets into molding-cantilevered -and diagonally placed-against the wall below finish out ceiling molding  - an unusual move- but the few hole punctures into wood molding was offset by the strength of the base of bracket against a boxed out (sheetrock) vent running behind rod.
