How to install this ceiling lamp.

I bought a whole bunch of stuff from a friend who was having a moving sale including this lamp and I'm not sure how to connect it



There is a golden nut which screws onto a bolt that goes through the center hole. There are also those little chains. The chains are connected to a brace which is connected to little cable clamps clamped on to small braided steel cables which I assume is what actually holds the light up.

Here is the ceiling box.

You'd hang a fan or a chandelier off that loop but I'm not sure how to connect this light. It doesn't weigh a ton but it does have some heft to it.

That light fixture is missing its back box.

Here, in the States, the fixture requires an all metal back box that would go up first.

If you want to hang that without a back box you'd need a fixture bar and a piece of 3/8" threaded fixture rod.

Dare I ask what a back box is?

I actually have the nut and rod that came with the light which would go through the fixture bar in your picture. But how would I connect that bar to the box? The box is a normal octagonal box with ears but I don't think they're supposed to support much weight.

Ok I bought the fixture bar. I was thinking I could secure it to the loop with a couple wraps baling wire and and use the chain in the light fixture as a failsafe incase for some reason the baling wire breakes

I don't recognize that type of box that you have in the ceiling.

Although this isn't your fixture..... the back box is the silver metal part that goes against the ceiling.

PJmax-

Its just a regular box like this:



which was placed on the form with the slab was poured (if you removed the plaster the box would be embedded flush with the ceiling). Unless I'm mistaken the loop visible in the inside of the box is usually secured to a piece of rebar on the other side

In case anyone in the future has this issue this is the piece you need. Found it at a hardware store

Is the wire thing real? Looks like something someone made. The ends are crudely formed. Not like something from a factory. I have never seen anything like it. I'm not even sure how to use it.

Yes, the " bent wire/stock. Never seen something like that. Did you make it?

No, I bought it at the store. But trying it out now, it doesn't actually work.

The guy at the store must have misunderstood me (he seemed to not really know what I was talking about, even with pics).

I think (not positive) its for hanging fans which would explain the rubber bit it came with.

So back to square one. How to connect a fixture bar to this?

Here is a better picture of a similar box in a different room

Yes that is a fan holder though not something used here and crudely made.

PJ has already shown you how and you have one piece. Now you need a threaded electrical nipple, nut and threaded finial.

No I have the threaded piece as well (came with the lamp). What made me a bit nervous about the approach you just illustrated is whether the box ears can hold weight. Is there a rule of thumb about how much weight they can hold?

I'll give it a try.

The box should be fine. A standard octagon steel box is rated for 50 pounds (22.6 KG) static load.

Thanks! That puts me at ease, I doubt it weighs even 10lbs.
