Reno:
Please re-read what I said above, as to GP recept spacings.

As I mentioned, a case by case situation, either on 'paper' or in the field.

Yes, IF it is called a wall/divider/partition, it will have 6/12 or >24" spacing. Solutions to provide code compliance are available, the issue most times is with the owner not wanting a device where is has to be by code.

BTW, the 'variation' is not a regular used item
