Unfortunately, there is no down rod to fit this fan. it is an odd size.  Unless you are able to install it with the 4 1/2" down rod that it comes with, this fan will not work for you.  After two trips to Home Depot and Lowes, we found that out.  You would have to buy a pipe and drill holes in it to make this fan work.  I love the fan but make sure that you have the correct ceiling and clearing for it before you buy.  It is going back today!!
