@Batto No, there is a much, much larger one than this for spitting cobra. Unfortunately, there doesn't appear to be a photo of the enclosure on the forum.
While we're here, though, what's your take on this enclosure? It is much longer than the snakes' body lengths and looks well furnished with deep substrate.
It looks like a nice set-up. One aspect some Cobra keepers would probably discuss is whether it is a good idea to keep more than one specimen together, given the chance of cannibalism.
