This might seem like a couple of silly questions and I hope it wasn't asked already. I didn't look since there are a lot of price list requests I don't want to read through.

1. Are these all freestanding and can they sit on top of something flat without being mounted?
2. Do they all have appropriate mount points where they could be mounted to a wall or hung from above with a chain?

Still holding up for everyone? I've just added a bunch of outlets high on my walls where I'm planning on eventually put a bunch of these.
