Does Ikelite dome port #5503 come with shade?

Hi,

Does anyone know if the Ikelite dome port (#5503) come with the port shade, or is it an optional accessory.

It seems near impoosible to tell, but BH Photo lists it as an accessory (as with the o-ring), so I am now very confused about which elements to buy.

Thanks, ds

It comes with a port shade, an o-ring, and a tube of o-ring silicon.

thanks!
