This item is note SC-B900SC but the picture doesn't corresponds to the photoflex web site. This item has 8 branch whereas photoflex one has 10 :
on photoflex web site , see : basic-metal-octoconnector .
I think there is a mistake with this item that corresponds in fact to the pic of SCB9108DSM on adorama web site ( consequently, the pics of this item is also wrong ... ).
Can you confirm that there is a mistake in the chosen picture on the adorama web site ?
The photo shown on this product page differs from the ring that I purchased. I photographed the ring I have, but there is apparently no way to attach it to this comment. Perhaps, I will try to attach my photo to the feedback section.
But ring I have has no inserts in the four attachment points. The ring has 8 outer-slot openings, two of which - opposite to each other - are segmented to allow for two more rod attachment points.
Also, the id of the ring is 5-31/32".
