noticed a ceiling LIGHT I had hanging over my door way for serveral years, I can't seem to get it to srew tightly to the brass back plate that is against the ceiling. It seem when I turn the nut up the threads it wants to go thru this back plate. THe whole thing sort of sways.
It appears that the opening of the back plate is larger than it should be. I can not afford to pay 65.00 to have someone come out and look at it. Will any one please advise me on how I may tighten the connection here.
