Exactly what I was looking for 👍
I really like the seal inside that the dampers seat against when closed. Fits perfectly in the 4" exhaust duct. Using it to seal out outside air from entering the indoor greenhouse through the exhaust fan duct.

Works as described
I put this on my exit exhaust vent on my portable air conditioner. It opens and closes as it should and prevents hot air from coming into the house very pleased and would recommend.
