This adapter fits a 14" x 14" opening. Please check your fan requirements. If it is 400mm x 400mm you need to purchase an adapter from our Euro Adapter listing.
Patent Pending adapter matches the contour of the OEM roof so a standard RV style vent mounts to a flat surface. Prevents distorting the roof sheet metal or vent flange and can be used as an aid for locating the fan. They are CNC machined out of UV and fire resistant expanded PVC. The fan mounts to the outside adapter.
Please note that not all of the Transit vans are the same in the Most Forward area and may require more adhesive if there is a gap or some sanding on the adapter.
The outside adapter will fit anywhere along the cargo part of the roof. Longer screws than came with the vent fan may be needed.
Check out the NEW Airplus vent fan we offer. It has more features than the Maxxair, a brushless motor and it does not rattle! By far the best!! The fan adapters also work with the Maxxair Deluxe series and the Fan-tastic Vent fans.
The vent adapter outside dimension is 16 3/4 X 16 3/4. If you are using a Maxxair vent fan our adapter fits the Maxxfan Deluxe series, other Maxxair vent fans have a wider flange. You will need a wider adapter. Please text Kim at 541-490-4292 for help.
The option with butyl tape includes 64" of tape. If the butyl tape is stuck to the plastic, put it in the freezer for 30 minutes. It will release, then let the butyl tape return to room temperature.

We make adapters to fit air conditioners and adapters for offset locations. Please contact us so we can verify size and location.
Roof Vent Adapter Install Tips
We recommend Sikaflex 221. Locate and cut the 14 x 14 hole. You can use the adapter as a guide to mark the hole. Stay clear of roof support beams.
Make a tape line 1/4" beyond the adapter perimeter. De-gloss the area with a Scotch-brite pad. No need to scuff, just dull the paint. Clean with isopropyl alcohol and let dry thoroughly. Blow dryer if it's wet and/or cold out.
Apply three 1/8" beads of the Sikaflex on the face of the adapter. Then, press the adapter down onto the roof until the adhesive oozes out the sides. It's not necessary to clamp. If you do, use several lightly set clamps and spread out the clamp force over the whole surface area.
Using the adhesive that oozes out, make a fillet around the adapter with a double gloved finger. Pull the tape within 15 minutes. Cure is fast on outside. Let cure overnight and then proceed with the fan install.
If you purchased our Interior Framing Strips, using the hole that you cut locate where the transverse strips need to be placed on the longitudinal strips. Assemble the interior frame with the 2" screws provided. Once the frame is assembled it will be glued to the interior side of the roof using Sikaflex 221. If the strips ordered are not bay specific, then you may need to cut them to the length of the panel you are installing it in.
We recommend using butyl tape for the fan install. Cover the fan flange with 1" wide tape. Place the flange onto the adapter and press down. Then drill pilot holes through the adapter and into the van roof. You may need the 4 longer screws provided for the corners. Tighten all screws very lightly against the fan flange. Some butyl will ooze out which you can trim off.
Coat the fan flange, adapter and onto the roof about 1/2" with self-leveling Dicor or brush-on Flexseal. Some sealants will melt the fan plastic so you might try it on a portion of the interior bezel first. You will cut a lot of that piece off.
Good idea to check the integrity and reapply the sealant every so often.
**Please note, if you purchased butyl tape with this order and the butyl tape is stuck to the plastic, place it in the freezer for 15 or 20 min. It will release, then let it return to room temperature.

Dometic RTX 2000 Air Conditioner Adapter for Promaster Van
Dometic RTX 2000 Patent Pending adapter matches the contour of the OEM roof so the air conditioner mounts to a flat surface. Prevents distorting the roof sheet metal and can be used as an aid for locating the AC. They are CNC machined out of UV and fire resistant expanded PVC. This same adapter will work with the RTX 1000 unit. Each of the options are sold separately.
The adapter for the Midship on seam, fits in the 15" bay but would require trimming of the beams .25" to fit.
Due to our process the 1" spacer is closer to 7/8", the .75" spacer is closer to 5/8" and the 1/2" spacer is closer to 7/16" .
We highly recommend our interior framing support system. Framing supports
AC Adapter Install procedure: We recommend 3m Window-weld or Sikaflex 221 adhesive. Locate and cut the hole. You can use the adapter as a guide to mark the hole. Stay clear of roof supports, obviously. Make a tape line 1/4" beyond the adapter perimeter. De-gloss the area with a Scotch- brite pad. No need to scuff. Just dull the paint. Clean with isopropyl alcohol and let dry thoroughly. Blow dryer if it's wet and/or cold out. Apply a good amount of the Window-weld on the face of the adapter. Then press the adapter down onto the roof until the adhesive oozes out the sides. It's not necessary to clamp. If you do, use a lot of lightly set clamps and spread out the clamp force over the whole surface area. Using the adhesive that oozes out, make a fillet around the adapter with a double gloved finger. Pull the tape within 15 minutes. Cure is fast on outside. Let cure overnight and then proceed with the AC install per the AC instruction. Seal the adapter and onto the roof about 1/2" with brush on bed-liner or Flexseal from the TV guy works well. Good idea to check the integrity and reapply the sealant every so often. Dicor self leveling sealant also works but looks a little messy.
Watch Hein's youtube video about this product and the choices.
Many customers ask what to glue the adapter and spacers and seal down with.
We recommend:
Sikaflex 221 between the van roof and the adapter,
Sikaflex 221 between the adapter and the spacer,
3M 90 spray between the spacer and the foam seal,
Bead of silicone between the Unit and the foam seal,
Dicor or the like around edges and on to the roof a couple inches.

Interior Backing Frame for vent installation for 14" x 14" opening
Frame that is used on inside of roof with our patent pending outside vent adapters for a 14" x 14" hole. This frame will not work in the rear-most roof panel in the Ford Transit 148WB regular length. We have shorter strips for that application, https://diyvan.com/collections/transit/products/ford-transit-inside-support-strips-for-148wb-and-130wb-medium-high-roof?variant=36888423465117
Provides material for screws to engage as they penetrate the roof metal. Made from expanded PVC so will not rot, mold or absorb moisture which is typically found around the vent. 14" x 14" inside opening and 16.75" x 16.75" outside dimensions. Available in two thicknesses. 1/2" and 3/4". 1/2" thickness is more flexible and will bend to fit curvature of roof if needed. 3/4" thickness is more rigid so will need a thicker bead of adhesive to make full contact with interior roof surface. Multiple frames can be stacked to make up difference between skin and head liner. Also see our framing strips if more space between inside of roof and headliner needs to be filled.
These frames are not contoured to the ribs, they are flat. Actual thickness may vary by - 1/8" due to variations in the material.
These backing frames may come in a "Grey" color.
Instructions for use: bond this frame to the inside of the roof skin with 3M Windoweld(TM), Sikaflex 221, or another equivalent adhesive. Use thick (1/2 - 3/4 inch) bead of adhesive to make up space between inside of roof and frame so it is level on the bottom Let cure and then install vent. Can be used to help clamp our vent adapters to outside and then later installed on inside as backing frame.
Interior Backing frame is not to be used together with the framing strips that we offer on other listings.
Construction and method of assembly is patent pending.
