I bought the 18" rod. It does not fit, the screwed portion is wrong and the cables are for something else. Will return this tomorrow. The Fan is beautiful and really enhances our living room. BUT, after over 2 hours trying to install it all we can do is Max light (not dimmable; or Max speed fan( not adjustable) or both max light and max fan. A Fan installer tried to make it work and could not. It does not matter, we only wanted it to look nice and provide light, we never use fans. I wish we could dim the light. Oh Well-3 stars
