Thanks DaleM! You have provided some great information! I am hoping that the ceiling trusses are not 2x2s, but maybe they are.

Thanks so much for the reply! As there is a large brass ring bolted to the fixture at each end, I thought that a good chain could be attached to each brass ring at either end and then hung from hooks that are screwed into the ceiling trusses. I am assuming that the trusses are 16 inches apart. Then ...

I have a double wide 1979 Lancer mobile/manufactured home. I found a beautiful but heavy, 32 pound glass and brass pool table light which I would like to install over my dining room table. Currently there is no light there, but I am thinking that if heavier chains were added to the outer brass rings...
