Easy way to support Spirit of 76 Fan Slices?

I’m shooting with Spirit of 76 Pro Line FanSlices/FanSweeps/GhostSweeps for the first time this weekend.

What are some cheap and easy ways to support these during a show?

We’ve drawn up plans to nail up wooden support boxes out of 1x4s, but I’m hoping this community can suggest a lazier solution.

Thanks!

I have used shelf brackets and sand which them tight on to a board. If you are on ground you can use big long nails two on each side should hold them just fine.
