Hey Jason, welcome back! It sounds like you are looking for the replacement lid for your Maxxair roof vent which we have with the part # MA05-30520. This is the replacement vent lid for the versions of the Maxxair roof vent that have the rain sensors like it says you have. Did yours get damaged?

If you are talking about it having the rain sensor to automatically close when rain is detected. No it doesn’t. But the Max-Air can be left open when it rains because it has about an inch and a half lib coming out of the roof and maybe 6” inches extending out from the opening to the rear.
