Fits a 14" x 14" opening.
The vent adapter outside dimension is 16 3/4 X 16 3/4. If you are using a Maxxair vent our adapter fits the deluxe series, other Maxxair fan vents have a wider flange. You will need a wider adapter. Please call.
The framing strips are expanded PVC and bonded to the roof with a thick bead of Sikaflex 221. They are more flexible than wood and plenty strong to support the vent and keep it from jiggling. We double them up when installing roof top air conditioners. They are essential if the span between the OEM roof beams is more than 18". They also provide a backing for the screws that hold up the vent interior bezel. They should be placed 1/4" away from the edge of the hole so the screws for the vent go into the strips. They are a generic size and will need to be cut to length. These strips are not contoured to the van corrugations.
If you order the framing strips they will come in a separate box. Dimensions of the side strips are .75" x 1.3" x 32". The interior backing frame is not necessary if you are ordering the Framing Strips.
We can make adapters for offset locations. Please contact us so we can verify size and location.
Roof Vent Adapter Install procedure:
We recommend 3m Window-weld or Sikaflex 221 adhesive. Locate and cut the 14 x 14 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 three 1/8" beads 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 fan install. We recommend using butyl tape for the fan install. Cover the fan flange with 1 1/8" wide tape. Place onto of adapter and press down. Then drill pilot holes through the adapter and into the van roof. If the screws are going to go into a roof support beam then drill a clearance hole in the beam. You only want the screw to engage the adapter and outer skin. Use a step drill to keep from plunging through the skin. You may need longer screws. Tighten them 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 brush on bed-liner or Flexseal from the TV guy works well. Some sealants will melt the fan plastic so you might try it on a portion of the interior bezel first. You'll cut a lot of that piece off. Good idea to check the integrity and reapply the sealant every so often. Dicor self leveling sealant also works but looks a little messy.

Patent pending adapter matches the contour of the OEM roof so an Artic Tern Skylight mounts to a flat surface. Perimeter of adapter matches vent 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 3M Window-weld or Sikaflex 221 adhesive for adhering the adapter to the roof. Additionally, 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 will include an interior support frame.
Outside dimensions are 23 1/2" x 33"
Inside opening dimensions are 19.75" x 27.6"
Artic Tern Skylight is not included.

When purchasing an adapter for a van please include a note indicating where you want to place the vent so we can produce the appropriate geometry to match the roof in that location. You are also welcome to send a photo to 541 49O 5O98. Please include your name if sending photo.
If ordering for a Sprinter we commonly ask for this measurement and information about the van:
1) Please take a measurement from the center of the large plug on the rear of the van to the back edge of the hole you will cut. Photo of the plug is below.
2) Please let us know which Wheel Base you have, 144 WB, 170 Regular or 170 Extended. The RTX opening is 15 1/2" long x 14 1/8" wide.

Insulate RV vent cover attached with magnets. Ripstop nylon facing with insulated core. Sewn in magnets keep cover firmly attached to interior bezel of the vent. Magnets and superglue included.
This fits the 14 x 14" Maxxair Fans.
MAGNET WARNING
Neodymium magnets are strong and can pinch skin. They may interfere with medical devices.
DO NOT LET CHILDREN PLAY WITH MAGNETS.
The magnets are brittle and can break or chip easily. Sliding magnets off the stack works best.
Broken magnets can still be used but we also include 2 extra magnets.
Keep magnets away from ferrous metals or they will jump to it.
Installation instructions:
1. Remove vent bezel by removing 4 screws holding it to ceiling.
2. Place vent cover on flat work surface making sure side labeled UP is visible and sewn on tab will be facing forward when back in vehicle.
This is very Important due to magnet polarity.
3. Place and align vent bezel on top of cover.
4. Distribute 12 magnets on back of bezel flange. The 4 round magnets are placed in the middle 2 spots on each side. They will snap to the locations of the magnets in the cover. See listing photo for location of magnets.
5. Make sure the cover stays aligned with the bezel.
6. Pick up each magnet and place a drop of glue on the bezel.
Then let magnet find it's place again. Do this for each of the 12 magnets.
7. Let glue set completely. Takes a few minutes.
8. Re-attach bezel to ceiling with screws removed in step 1.
9. Cover will now snap onto it and be held by magnets.
10. Front panel with tab can be folded over to allow partial 1/3 opening.

Sold as a pair, these adapters are for upgrading the speakers in the the front doors of the Promaster van. The factory door panel and speaker grill is retained for a stealth factory look. This is a crucial step to enjoying better sound quality in your van.
The adapters were designed in 3D CAD and they are machined on a CNC router. The holes in the adapter are perfectly located and countersunk to mount over the factory posts and be secured with the original screws. Then you drill holes in the adapter ring for your speakers and secure them with sheet metal screws. We highly recommend installing 3M Thinsulate(TM) behind the door panel at the same time.
Material for the adapters is 3/4 thick expanded PVC. It won't absorb moisture like MDF or wood and holds screws well without splitting. O.D. is 6.5" (165mm). Thickness is 3/4" (19mm). There are 3 ID sizes to accommodate the cutout diameter needed for the speaker. Please continue reading to learn more about speaker sizing...
While shopping for speakers look for 6 1/2 or 6 3/4 speakers. COAX are the best bang for your buck and component speakers are potentially the best sound but involve replacing the dash tweeters and installing a crossover. Most 6 1/2" speakers require a 5" ID cut out diameter which is the size of hole the speaker will drop into. The corresponds to one of our spacers on the drop down list.
There are also what the industry calls 6 3/4" speakers which allows for a bigger cone and improved base response. These speakers require the 5.62 or 5.75 ID cutout diameter (hole). We have 5.62 and 5.75 ID adapters for these speakers. Do not choose speakers with thick cast aluminum or plastic frames with protruding terminals. These are too large to fit into the smaller hole in the door sheetmetal. It is best to choose a speaker with a thinner formed metal frames and terminals that can be bent slightly should they interfere. Also do not choose a speaker that has a thick frame above the mounting face. This will interfere with the door panel. Overall height of the spacer and speaker should not exceed 1". The door panel can be trimmed to clear a taller speaker. Please contact us if you need help choosing or verifying the fit of a particular speaker.
Here are some specific suggestions of speakers that should fit.
Rockford Fosgate Prime R1675X2 = 5.750 ID
JBL GT7-6 = 5.625 ID
Please note that we are able to make custom sizes.
While you have your door panel removed it is a good idea to put some thinsulate in it? Video is on a Ford Transit but it is the same process.
