That’s interesting now. Would they give enough space to fire somewhat to the sides or just straight ahead?

That I don’t know. Maybe there are some photos online of the rooms that has them in the pics. Though, if we’re talking about a lower floor, a shooter wouldn’t need a whole lot of up-down room since the angle wouldn’t be as much. That is if the ventilation strips could accommodate a weapon in the first place.
