Interior Roof Vent Adapter

Mod: Roof Vent – Part Two

Installation of a roof vent in my 2016 Ford Transit requires support adapters, both on the inside and outside of the van. This interior adapter is made of wood and will be connected to the vent by means of bolts and nuts.

Considerations

Like many of the vans that are on the market today, the Ford Transit has a corrugated roof, that is awkwardly sized and not in line with the standard sized RV roof vents. Third party adapters are available to make the job easier, but these don’t fit the popular location between the two rear ceiling braces.
The MaxxAir vent is designed for a minimum roof thickness of 1-1/8 inch (and a maximum of 6-1/2 inch). This wooden adapter helps to build up to an acceptable thickness at the ceiling opening. I used some leftover pine to construct the frame and made many trips to and from the van, to check and fit the pieces.


The Project

  • I use four pieces of wood 1” x 1¼” x 16½“.
  • Scribe the roof edge onto the wood with a compass.
  • Then cut the wood on a bandsaw or scrollsaw.
  • Sand as necessary.
  • Route the profile of the ceiling brace into the wood.
  • Cut the lap joints on all the pieces.
  • Use wood glue to put the frame together.
  • Fit the workpiece constantly, to avoid major mistakes.
  • I give it a couple of coats of polyurethane for protection.


Conclusion

A simple project that can be made with simple hand tools, but having access to some woodworking machinery will make life a lot easier and more exact.
