When the old vent lid cracks or starts leaking, this white, wedge-shaped polypropylene dome puts things right again. It’s made to replace the cover on Ventline Ventadome roof vents, restoring a solid seal that keeps out rain and UV. The plastic construction resists weathering better than brittle old covers that have been baked in the sun for years.
No guesswork here—this replacement dome fits Ventline Ventadome roof vent models V2092, V2094, V2119, and V2128 made after 2008. The shape and continuous hinge line up exactly with the factory design, so once it’s clipped in place, the vent opens and closes like new.
The lid covers the standard 14-1/4" by 14-1/4" rough roof opening used across most roof vents. That makes it a straightforward swap for old or storm-damaged lids that have the same hinge type. Just check your hinge and model number, and you’ll know it’s the right fit.
The white color gives a clean, neutral look that blends well with most roof finishes. It looks tidy from the outside and keeps the vent area from heating up the way darker covers can. Simple, durable, and built to keep things sealed and protected up top.

Today we're going to be taking a look at the Ventline Replacement Dome Assembly in white, part number BVD0449-A01. It's also available in smoke, part number BVD0449-A03. This is going to be a direct replacement for the lid on your model number V2092, V2094, V2119 and V2128, Ventadome Roof Vents. It has the same web shape and it's made out of the same polypropylene material. Over time your lid may crack, break or fade. We're going to show you how to replace it. Now of course this will be in your RV, but for demonstration purposes, we're going to show you right here.
We'll flip it over and this will be as if we we're looking up. First thing we want to do is go ahead and remove the screen. We've got these little tabs surrounding it. We can actually just push those out and begin taking it off. All you're going to need for this job is a Phillips-Head screwdriver. Let's go ahead and take off the knob.
Once we get that screw loose, we can actually just pull up on the knob just like that and set it aside. For our tray here, we just need to push in on each side inward. We've got some teeth that we need to get around, but then it should just pop right on out. You can see the two teeth here. Then we've got our switch. If you'd like you can disconnect it, we're going to leave ours attached.
The other two wires here will be connected to your power in your RV. Then we can grab our Phillips-Head screwdriver again and we're going to remove our arm assembly. Now we'll need to take these screws all the way out. With those loose, it's going to allow us to remove our arm from our lid. We can just slide it off like so and just kind of leave it set there. Then it's going to allow us to remove our lid from our vent assembly. Now this portion will be on top of your RV.
You can actually lift up on the non hinged end of the lid all the way up and then take it off. We can grab our new one. We'll locate the hinge side, go ahead and turn it over, line it up and then turn it over like so. Now we can go back inside of our RV. Back here on the inside we can reconnect our arm assembly. We'll just need to slide this on to the portion right here just like that and then position it over our holes. I've gone ahead and reinstalled my other components. Let's go ahead and test it out. I'd say it's working pretty good. That's going to complete our look at the Ventline Replacement Dome Assembly.

Exactly what i ordered.Fits perfect.
Delivered to Canada no issues.
Great doing buisness with etrailer
Fits great. Pretty easy installation. Add a drop or two of plastic-compatible oil on the slide to get the smoothest operation.

dome still in one piece no cracks
I bought two (2) of these and they fit better than the originals! Great product and took about 20 minutes for both.
Not a big deal, but the video eTrailer shows on how to do the replacement isn't 100% correct. The video work is done on a table and doesn't mention that the inside trim ring on the fan needs to be removed to get the fan out plate out.
Worked great. Followed your install vi deo.
fast shipping!
Easily installed but if you have to remove the insert in the interior just beware that they are easily broken and they are not cheap to replace.
Fit perfectly and was a quick install. Shipping was really fast!
Great product. Instillation instructions were very informative.
This was a really easy replacement. Professional company with a real person to help with questions.
My fault I ordered the wrong one that the Moix dealer told me was the right one it was not I sent it back to you at a cost of$18 but like u said my fault I have since ordered the right one with the help of Adam it fits perfect.
Good quality fast shipping
These guys are awesome.. It appeared there would be a delay in shipping so they sent out duplicat to make sure I received while I was still at location.
Thank you Joshua!!
Perfect fit. Video below the product with install instructions was a huge help. Will order more when the other vent covers start to go.
Direct replacement for Ventline V2394, and the install videos were helpful.
Everything was excellent and super fast shipping.
The replacement vent line domes for my rv arrived on schedule, were well packed and in good condition. As soon as weather permits I will install them. Ordering from Etrailer is as good as it gets!! ??

Thanks for the kind words Lester, I love hearing how we are doing things right. What kind of camper is this going on, and what trip are you looking most forward to this camping season?
perfect replacement- excellent communication and timely shipping on my order- Thanks!
The product itself is great. I cannot find (replacement)hinges for it. I am going to have to change it out for the other type I think.

Hey Bert, unfortunately there aren't available replacement hinges. Wish I had better news for you!
The replacement vent cover fits great, seems like a good product but maybe a little flimsier than the original but should do the trick.
We described the vent as exactly what we needed. And what year our camper was? And that was what was brought up. But it is not the proper bracket style or vent bracket.However, you want to say that to fit.So now we have to figure out how to return your product
I went to a local trailer parts store and they said they don't make the correct sized vent dome for my trailer. I was really bummed out. Then I checked with etrailer and they said they have the part that would likely fit. Low and behold, it was an exact fit! etrailer is the best!

Perfect fit and better quality than the original vent cover.
The vent cover is exactly as described on the etrailer website.
Wish i would have known about etrailer before I spend time going to RV dealers and checking the internet which was no help.
The vent cover are a perfect fit and very easy to install>
Great product, fit exactly on Cougar 320RDS as a replacement for the Vendadome bathroom vent cover.
