Patent-pending adapter matches the contour of the OEM roof so an Artic Tern Skylight mounts to a flat surface. The perimeter of the adapter matches the vent's cover for best performance and appearance. Prevents distorting the roof sheet metal or vent flange. Can be used as an aid for locating the fan. Adapters are CNC machined out of UV and fire resistant expanded PVC. The vent mounts to the outside adapter. The outside adapter will fit anywhere along the center cargo area of the roof. We recommend that you seal the adapter and roof light after it is installed with a membrane sealant such as Dicor.
If you are ordering this for a Sprinter we can produce them for the NCV3 or VS30, 2007 to present.
The order may include interior support strips if needed.
Outside dimensions are 23 1/2" x 33"
Inside opening dimensions are 19.75" x 27.6"
