DIYVan’s vent fan adapter matches the contour of the OEM roof, creating a flat surface to mount a standard RV style vent fan. The vent fan adapters are CNC machined out of UV and fire resistant expanded PVC.
These adapters are designed to work with the Maxxair Deluxe Series Fan (7000K & 7500K) and the Fantastic Fan; with a 14" x 14" opening.
Outer dimensions of vent fan adapter: 16 3/4 x 16 3/4”
Designed for the Ford Transit; High and Mid Roof Only.
Most Forward Position Adapter:
The Most Forward Position adapter is designed for those who want to push the fan as far forward as possible to maximize roof space behind it. This position is ideal if you need to free up more space for other rooftop accessories or installations. However, it's important to note that using this adapter requires cutting into the roof seam on top of the van. This modification is essential to ensure a proper fit and secure installation.
Standard Position Adapter:
The Standard Position adapter provides flexibility and can be installed anywhere else along the roof of the Transit. This option is perfect if you prefer not to modify the roof seam or if your setup allows for a less forward position.

These adapters are great, they sure allow to clean and tidy look after the the caulking is finished! We used them in our last van build as well.
I have a 2022 Ford Transit high roof, and using this most-forward adapter requires that the frontmost edge of the hole you're going to cut (14" x 14") would cut through the roof support by about 1/4". To combat this, I had to move the template backwards on the roof about 1/2". It worked perfectly well still and I filled in the extra gaps I created on the roof using 3M window weld. All in all, no difference but just keep that in mind.
