Discs? You mean the dummy plugs for when dorade is not mounted? Included.
Also the ring that is mounted to deck with screws or bolts is included. But the plugs and also the vents themselves snap in the ring base (or whatever it is called) rather than screw in, allowing the vent to be directed according to wind
direction. If your ring base is threaded, you would need to replace with these. All components were made by Martec, so are meant to fit together. Possibly no other brand is the same.
The bottom ridge on the "male" part of the vent seems to me to be raised more than necessary, but would better hold the vent in place. I've never forced them together.
