Hi -- I have for sale a 10U Calzone Cases (look them up -- in business since 1952) rolling shock mount rack case.
The rack depth is 16" (between the covers) with the overall depth being 23". The foam has been removed from the rear cover to allow deeper rack units / cables / etc to fill that space. If you wanted you could get new foam to replace it.
Overall width is 24" and overall height is 24".
The unit has dual heavy duty handles on each side, and heavy duty casters to easily roll around.
