Question:

i have a wells cargo enclosed trailer with a roof that is slightly curved. is there a vent type that has a mounting flange that is pre-arched to fit the roof surface?

If the roof on your enclosed cargo trailer isn't rounded too much then you actually don't need a pre-arched roof vent as you can see in the attached picture of the Ventadome # V2092SP-28 installed on an enclosed trailer. If your trailer is has more of a severe arch to it than what you see in the picture then you would have to find a way to support it as there aren't any specially designed vents for that.

In addition to the picture, I have also attached the installation video that we took of us performing the installation so you can check it out.

I'm looking for the front radius cap where upper lights are one . Can you get that part or stock it ?

@JimK We unfortunately don't carry anything like that. You'll want to reach out to your local trailer shop (or even the trailer manufacturer for your trailer) for something like that.
