Description:

This aged ceiling fan finally gave up the ghost and needed to be replaced. Some designer, decades before, had thought of me (as well as the installer). The designer place a hook on the mounting plate shown above left. The function of the hook became apparent when the bolts were removed from the ceiling and the full wieght of the fan started toward the floor (above right). That simple design feature was very convenient and appreciated.
