Sea Frogs Extension Adapter Ring V10 for 6" & 8" Dome Ports

90mm Bayonet|61mm Extension|Polycarbonate|6" & 8" Dome Ports

The Sea Frogs Extension Adapter Ring V10 for 6" & 8" Dome Ports sets the distance between your lens and the dome, so the port focuses where it should. It adds 61mm (2.40'') of extension and mounts on the 90mm (3.54'') bayonet shared by the housings listed below.

Extension rings work with dome ports only — 6" & 8" — and cannot be used with flat ports or stacked with another ring. Each dome port states the ring it needs, so match the two before you order.

FAQ

What does the extension ring do?

It sets the distance from the lens to the dome's focus point. Every dome port is designed around a specific ring length, so the pair has to match for the port to focus correctly.

Which dome ports does it fit?

6" & 8" Sea Frogs dome ports with a 90mm (3.54'') bayonet mount. The port's own listing names the ring it takes.

Can I use it with a flat port, or stack two rings?

No. Extension rings are for dome ports only, and they cannot be stacked — one ring sits between the housing and the port.
