Trying to replace a pretty old ceiling light fixture, and after removing the plate that hides all the wiring, etc are, i found no metal outlet box. Instead, there is this really strange setup:
There is black round plactic disc (about 2 inches in diameter) which has a
1 inch long srew type rod sticking out of it. Then there are the appropriate wires around it. But thats it. There is no outlet box or anything at all.The light i want to replace it with comes wtih a hanger bracket and the instructions tell me to install this hanger bracket onto the outlet box. Since there is no outlet box, i don't know what to do. What are my options?
Thanks.
