Maybe. We got a prototype of a metal bracket with holes for two multiples
from our (metal parts) manufacturer. We will send it to the case
manufacturer to built a suitcase prototype with this metal bracket instead
of the wooden bar. I have no idea if it will work but keep you informed. It
could be used for both 6U and 9U cases.
