I use a lot of PCB modifiers and the foldable softboxes have a Balcar removable adapter from the speedring. I replace it with this item: http://www.bhphotovideo.com …ails&Q=&sku=854850&is=REG

Thanks.
That's the one I have that was used to mount the foldable on the Speed Pro bracket in the picture above. Couldn't remember where I got it.
