Photoflex Large softbox silver nxt
 

I have a large photoflex box that I use with a 1000w starlight, I am having problems with it rotating. What do other users do to keep it locked down. I see velcro around the box but it is kind of cheesy. Is there a way to lock the adapter connection to keep if from rotating, my box sits diagonally from where I need it. It is probally so simple but I am just missing it.
