Where can I find a cage?

I have taken tours of several large and impressive bases, which gave me many ideas for my own. One thing I saw was goldish colored cages, the type that might hold a large animal.

I have looked through every list in the Base Editor, and have yet to find it. This leads me to suspect that the cage is a personal item, but I don't know how to check on that. Does anybody know how I can get/create these cages?

Thanks in advance!

I used floor lamps. Like this.

EDIT
I also did a small railing with the bankers lamps but I don't have an upto date photo of the base. I must do that. I'm on Guardian if you want to have a nose around.

There are no actual cage items. You can do some interesting things like Capa did using existing items that are tall and bar-like. There's a few that work in the arcane items and a few in the tech items so you can achieve different styles.

Capa_Devans: That's not what I had in mind, but I like it so much that I might use that in another part. I am always amazed at the creativity that can be seen with ideas like that.Thanks!

TheUnnamedOne: I am fairly certain that the cage I saw was one piece, and if I recall it was hanging from the ceiling. It was just big enough for a single person to get in, with the top open so one can jump in.

Meantime I will experiment with Capa's idea, and see if I can get it to produce similar results.

Thanks!
