If your vent lid is cracked, faded, or missing, this replacement top cap brings it back to full function. It’s designed specifically to replace the cap on the MaxxAir MaxxFan dome roof vent (model MA00-03812B), so the fit and seal are right the first time.
Made from sturdy plastic, the black cap shields your vent opening from rain and debris. It’s built to handle regular exposure to sun and weather, keeping the vent protected and extending the life of the system.
The black finish blends in with existing MaxxFan hardware for a seamless look. Once it’s installed, the vent looks finished again instead of patched together.
Designed as a direct replacement, this top cap installs easily on the existing MaxxFan dome setup. No need to modify or guess—just remove the old cap and set this one in its place.

Hello, everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this replacement top cap for your MaxxAir MaxxFan Dome Roof Vents. Now this part here replaces the top cap on your MaxxAir MaxxFan Dome Roof vent. That roof vent we do sell separately on website. It's part number MA00-03812B. I just wanted to pop up an insert to show you what that vent looks like.
You can see this cap on the top. It is a black plastic construction and this cap is designed to install to the top of the roof vent and it covers the vent opening so that you can use it in rain or shine. The cap will help block rainwater and other debris from entering through the vent and damaging the interior RV or camper. It also eliminates the need to have to install a separate vent cover on your RV. Now this does install, you can see the two holes right here.
Now the hardware to install this is not included. We do sell that separately. Diameter on this is gonna measure 8". And the overall height, it's gonna be right at 1-3/4". But that should do it for the review on the replacement top cap for your MaxxAir MaxxFan Dome Roof Vents.

Fast shipping. Great communication. Th anks
I used this cover to replace the cover that was 49 years old on a 1976 GMC motor home. It fit perfectly. I was sure I was going to need to replace the fan to fix the broken the cover. Prompt delivery and a great fit. Thanks!
