How to Select the Correct Replacement Vent Dome Cover for a Trailer Roof Vent

Measuring the vent is the first place to start. Most standard vents are 14-1/4 by 14-1/4 inches wide, 14 x 14 inches wide or 13 x 14 inches wide. Next if the manufacturer name is on the vent that will help. Finally, you will need to look closely at the hinged portion of the the vent.

If there is a rolled metal hinge attached to the vent cover like on the Ventline Replacement Smoke Dome Assembly, item # BV0554-03, that you referred to then that is most likely the correct vent for your trailer.

Basically the easiest way to select the correct replacement cover is to remove the existing cover and match the hinge and lift bracket to the photos on our site along with the dimensions. A link to all of the replacement vent covers is provided to match up with your cover.
