Do not buy this fan. I have been trying to install this fan for two days now. The hardware that comes with this fan is not user friendly. I have had to modify the brackets that hold the fan blades onto the unit. The screw heads do not fit into the holes of the blades. There are other things that have been a fight but having to modify anything brand new is a hint that you have purchased something that is not of a quality value. This must be why they only sale this on line instead of selling it in the stores. If I would have purchased this at my local store you can bet that I would have been back talking about swapping for a different fan.
