Tiger, I just hung a chandelier like that. How deep is the canopy? Mine had a nice 2" deep canopy with a set screw. I went to ace hardware and got their smallest hook with machine threads on it. It was a 1/4-20. Then I installed it on a flat fixture strap using two nuts and two washers. It only stuck out about 1", leaving plenty of clearance for the canopy.
If you don't have a deep canopy, you could get some fender washers and fasten the hook thru the center KO on a metal 4/0 box.
From the title I thought this thread was going to be about one of my personal pet peevs... The fact that it seems most Italian products are never actually put together by the people who design them. On several occassions I have found that a screw or something else for assembely or attatchment was impossible to get to when either assembeled or attatched. i.e. one impossible without the other, and impossible to do in sequence. Of course even if you do translate the provided Italian instructions the dont say much.
Or my other favorite having to modify every fixture to hang on a 4/O or 3/O box. As it seems the Italians just nail fixtures to the wall or cieling then plaster right up to them sans box. Although they are selling to the US market - sometimes they just chuck a coverplate in and let you wing it. Otherwise I go get my own down at one our few local fixture shops and forced to make due, as it sounds like Tiger has.
When ya say it needs a 'hook' what exactly do you mean? whats the fixture look like?
The shop listed below does a lot of custom work, and can locate a plate for you, or refinish one to match. Even get it listed if need be. Unfortunely they are a bit low tech in way of web presence - and I've never had to deal with them at long distance....
