What is the Standard Roof Vent Size Opening and Are They All This Size

Expert Reply:

There is a standard vent size opening which is 14" wide x 14" long but not all of them follow this rule so you will need to measure to be sure. The Camco RV and Enclosed Trailer Roof Vent Cover part # CAM40453 fits the standard 14" wide x 14" long roof vent opening. This cover will allow you to keep your vent open at all times even in inclement weather.

I have attached a review video of the roof vent cover for you as well.
