Could this hold a small double dome

I wouldn't worry so much about the size (as long as you wanted the domes side-by-side and used the metal hook in the middle), but I don't know what kind of weight the bracket can support.

The arm that sticks out is 6 inches long. And my lamp is a medium size one. With not much room left. It would be difficult to fit 2 on one. But my small tank would easily hold 2 of the brackets.

It could structurally, but the top is only 8" wide. It could tip pretty easily.

No. Too small. Strong though. They are too thin or bottle cap. Could probably do it if you doubled it up or even tripled them by stacking .

Possibly, but I would not buy it for that purpose. It's really reliable for smaller items.

This may would hold a small half helmet. I do not believe it would work well as a helmet bag.

With some modification yes, but a single 2x4 in not strong enough to use to full capacity .

Yes, I have a larger double dome for 150 watt blubs. Just make sure the glass is clean and dry before sticking it on.

It is plenty big enough for one. I don't feel it is big enough for doubles.

Possibly but I don't think its deep or stable enough to hold anything large or heavy.

Haven't tried it, but I don't see why not. Of course it would have to fit within the dome.

Just guessing here, but I would say no. Seems like the "dome" would collapse in on itself, because of the plastic joints. I wouldn't do it.

No, it would be too small. The weight limit on this particular one is up to 25 pounds.

I think you could make it smaller, but you would lose some of the stability. The even sides help keep the cage balanced.

I have a small 13" one on mine. No problem. I think it could hold a bigger one but not a BIG one.

Its 3.5" in diameter. After seeing your question, I tried again to separate the dome from the base and was able to, although a wire from the LED to the battery terminal broke loose. I'll try soldering it back. It should mount OK after that. Thanks.

Yes, it could. Although slightly curved, the weave pattern would grip most smaller glasses and plates. Might be a problem if you want to put a large center piece on it, as that would wobble.

No, its not scored that small. If you already have the metal supports that small, you can just swap the rubber like I do.
