Ventline Ventadome Trailer Roof Vent Mounting Hole Measurements
Question:
Can you tell me the distance of the bolt pattern? I only have 15 between roof braces. Also, do you sell a smaller vent? Thanks

Expert Reply:
The Ventline Ventadome Trailer Roof Vent - Manual - 14-1/4" x 14-1/4" - White # V2092SP-28 is the standard vent size. It is not uncommon to have roof braces that are 15 inches apart. This vent has mounting holes that measure 15-1/4 and 15-3/4 inches on center. I've attached a photo of the measurements I took for you.
I recommend the Installation Kit # 344270KITW for the installation of your roof vent. I've attached a video to assist.
We do not carry roof vents of any other size unless you drastically change the style to # VP-543SP or # 9106-2756.
