Replacement Dome Lid for Ventline Trailer Roof Vent


I need a white replacement dome for my 2010 trailer vent. The vent is a Ventline VD0436 I believe - Which replacement dome will fit? Thank you for your help

I wasn't able to find any references online regarding the VD0436 vent you mentioned, but luckily enough it's usually easy to find a replacement if you know a few things about the vent installed in the roof as mentioned in the linked article.

You'll need to know the size of the opening in the ceiling (see photo), you'll need to know what type of hinge the vent is compatible with and the desired color.

You'll want to remove the garnish or trim piece and measure the length and width of the hole in the roof. Most commonly, you'll find it's 14-1/4 x 14-1/4 inches. Next, choose the style of hinge. Is it continuous? Is it a 3-point? A 4-point? Ventline typically uses a continuous hinge.

For a white replacement dome with a continuous hinge for a 14-1/4 inch square opening, you'd need # BBC0530-01. If your existing vent is a different size or uses a different hinge configuration, let me know and I'll continue looking.
