Sea Frogs Extension Adapter Ring V.7 for 6" & 8" Dome Ports

Sea Frogs 90mm Bayonet Mount| 37mm Extension Ring

The Sea Frogs Extension Adapter Ring V.7 adds a 37mm (1.46'') extension for use with Sea Frogs 6" and 8" dome ports. It features the 90mm (3.54'') bayonet mount and fits most Sea Frogs underwater housings, excluding the A6xxx and RX1xx series models. If you already own a Sea Frogs dome port, there's no need to purchase a new one to fit a different lens—simply swap the extension ring for a perfect setup.

Please note: Extension rings are not suitable for flat ports and cannot be stacked.
