Availability of Roof Vent for 13" x 13" Rough Roof Opening


Does anyone make a roof vent for a rough opening of 13inch x`13? we are trying to repair and emergency response trailer and not only is the rough cut hole 13x13 but they built an aluminum frame for it so increasing the hole would be difficult. Its a 2008 Featherlite trailer. Not sure on the model though.

All of our standard roof vents, such as the Ventline Ventadome # V2092SP-28, are designed to install into a 14" x 14" or 14-1/4" x 14-1/4" rough opening. This is the standard vent size for trailers and RVs so I'm not aware of one that is designed for a 13" square opening.

Unfortunately your only option is going to be to try and expand the existing cutout on the trailer to accommodate a new vent like this. This will also make it easier to replace the unit down the line or even upgrade to an AC unit at a later date since they typically require the same opening size.

I have attached an installation video for this particular vent that you can also take a look at.
