As mentioned in early post l have a ceiling mounted fan but have a ducting problem also.The fan l have brought is about one/eighth of a inch wider in diameter and will not fit into the ceiling ducting.l cannot remove it has this is in flats ,and the ducting bends a few inchs inchs inside the ceiling and then connects with the rest of the ventilation system.l,m just a fraction to wide in diameter with this new fan,any ideas.
