Question: what are the distances between holes of the arms?
Document: What I couldn't find information anywhere about whether these arms are universal. The box says that these arms fit most 52" fans. I'm not 100% sure what that means, but the holes in these arms lined up perfectly with my old arms and I have a pretty standard generic ceiling fan.
These Westinghouse Fan blades didn't quite fit like the originals. They fit  length wise but the screw alignment was off by a little bit. Luckily, my neighbor and handy man  was able to drill one screw hole opening by maybe a millimeter or more, so  that the screw holes  aligned. He was able to replace two of my original blade arms, the first one that broke off and another  blade arm that was bent.
The Blade Arms fit tha fan blades perfectly,The product arrived on schedule.Great quality, finish matched perfectly.There are 5 Blade Arms in tha set,you can change them all so they all look new.I did. The holes lined up perfect withthe motor holes my fan is a 52inch fan.I would definately recommend this product.P.S. If you search online for WestinghouseFan Blade Arms measurements you will find a chartwhich shows the measurements before youmake your decision.
These Fan Blade arms were exactly what I needed and they look beautiful on the plades. The price was perfect.
These fan blade arms worked just fine on my older model fan. I did have to change all five, because they do have a slightly different angle than the original.
I gave it 3 stars because I wouldn't have been able to repair these blade arms myself. If I didn't have my neighbor I probably would of call a fan repair person and it would of cost me more.
This set had to be modified by grinding about 1/16 inch to make more clearance on my fan and prevent rubbing. This set is shorter by about one inch than the original, and apparantly made for fans designed to be installed on low ceilings.The instructions in the package make it clear that driling new holes in the fan blades is expected. However, none of the advertisements mentioned this or linked to a copy of the instructions.
My twenty-year old ceiling fan (no brand name) finally dropped a blade unexpectedly one day, so I ordered these replacement brackets. The motor end of the brackets fit perfectly, but I had to mount the blade end using the center screw, then drill new holes for the bracket ends on either tip. No worries as it took only about 30 minutes and my trusty ceiling fan was spinning smoothly again.
It is absolutely essential to know what the spacing of the attachment holes is at the motor hub. Without that bit of data, one is just shooting in the dark. There are several different spaceings depending on the manufacturer. It is rare to locate this vital bit of information from most mail order suppliers. My luck has been much better when ordering from stores that specialize in fan parts. The brackets are fine if you get lucky and get the proper spacing. It is NOT standard to all fans.
