If you have Elinchrom strobes they have this ridiculous brand specific 7mm umbrella shaft mount. Standard is 8mm and there is no step-down adapter made. I was just short of starting to hack my umbrella shafts and modify them when I looked online one more time and stumbled upon this video. Apparently, and I can't say all Elinchrom heads, the heads have a secondary umbrella shaft mount. Here is the YouTube video that I found out about it.

My Elinchrom lights have been almost perfect with the exception of the umbrella 7mm issue. Now they have reached perfection with this new knowledge.
