Nauticam N120 extension ring 20mm II
20mm II extension ring with lock and internal rotating bayonet system, the same as used in Nauticam housings, so that it does not require turning the ports for mounting on the front.
This prevents gasket friction when mounting and rotating the ports or rings, which helps prevent the gasket from coming off during mounting as well as minimizing wear and tear.
Compatible with Nauticam housings N120 bayonet system.
