I had a ceiling light and it had a metal bar and a electrical box. The home is not that old but The electrical box was not ceiling fan compatible so I removed the box. Now the bar is solid I could hang off the thing and it would not move and believe me holding me is more weight than the ceiling fan. To install the ceiling fan with the bar and electric box that is ceiling fan approved I have to saw out the existing bar and put a new one in. My question is why do I have to do that?? Isn't there some electrical box that I can buy that will work for the ceiling fan and the existing ceiling light bar??? If there isn't there should be But please tell me there is cause I don't want to saw the existing metal bar in pieces.
