I don't need extra space. It's a goofy little serrated hard plastic piece that Fusions have. Once a year I'll catch the rope on the tweeter and brake the insert. It was no big deal until Fusion went under.
I'm just going to bring them down and have the second clamp added to them and that will be the end of it.
Don't quote me on this, but I believe they are same clamps monster tower sells. I think the rubber inserts from them would work. If you look at fusion light bars and monster tower light bars they look so so similiar.
