Do you carry roof vent covers. The only number i can find on the cover is ventline VDO434.

Expert Reply:

We sure do Ron. The VDO434 part number you found is for the screen component only, not the entire Ventline vent assembly. I can help you identify the correct replacement vent lid for your trailer by matching up the type of hinge on the lid.

Vent lids come in three basic hinge types, 3-point, 4-point and continuous. I attached a photo below that will help you determine which hinge type is used on your vent.

For example, for a white wedge type lid with a continuous hinge you can use the Ventline item # BVD0449-A01.

What kind of hinge does your vent have?

You can add this information, along with any other questions you have, where it says Add Comment.

@Ron Maybe? What kind of hinge does your vent have? The Replacement Dome Assembly item # BVD0449-A03 has a plastic continuous hinge.

Replaced 3 using the 3 hinged model. Pretty easy after the 1st one. Disconnect the interior assembly first, then climb on the roof to remove the dome. It will work either way just be careful not to tweak the Opening/closing mechanism too much. The screen etc snap in place.
