Chimera Quick Release Speed Ring for White Lightning Ultra

I have the large (54x72) non-slim version of the Chimera softbox as well as the medium (36x48) version. While the medium one fits nice and comfortable on my strobes (Einsteins), the large one seems a bit too heavy and I worry that it will one day fall off the strobe. However, it hasn't fallen yet. There does appear to be three screw holes at the bottom of the ring (can't see in the picture). I'm thinking that there must be an additional support fixture that will allow me to attach the softbox to my light stand in order to take the weight off the strobe. I just need to find it. Other than that, this thing works very well for medium and smaller sizes. I don't have to worry about losing an eye during setup and teardown. If you're the type who leaves the poles in the softbox, then the setup is even quicker. For those who aren't sure how it works by just looking at the photo, the connections for the poles swivel 90 degrees forward. Once all the poles are connected and tightened, you pull back on each pole so that the connections swivels back outwards and locks into place as shown in the photo.
