What's hilarious is that if there is a one-inch wide gap running through the cloud making each section less than 4 feet wide in the least dimension then it will meet the obstruction rule as long as the space below the overhead sprinkler meets that rule. Good design? Probably not. Code acceptable? Yes. And I have a written informal interpretation penned by Mr. Brown to that affect. It regards ducts specifically but still a horizontal obstruction.
