One port is the 6 inch dome port (Model 5503.50). The other port is a flat port with a focus nob. I don't know the model number of the flat port and I contacted ikelite and they also did not know. All I know is that it works with my Nikon 60 mm macro and the length of the port is 11.6 cm.
Ports are in great condition and I am including the neoprene covers.
$250 for both ports.
