I have been looking for a secure way to attach my Norman 400B flash's battery pack to a light-stand for outdoor portraits. I tried to make a few things but nothing worked well, and the huge cluncky thing would swing and sway and annoy me whenever I moved the stand. But I figured having it attached low on a light-stand would keep it from blowing over on a windy day.
So I finally figured I would bite the bullet and pay the US$78 for the Norman 810863 Quick Release Stand Mount Plate. Crazy overpriced I thought, well it works perfect and was worth every cent.
I had to call Norman to see if I had installed it right, I had it upside down... duh.
