Patent Pending.These adapters solve a unique problem related to fitting or replacing the vent on an Airstream trailer or motorhome. The roof of the Airstream is curved and the vent flange is designed to seal against a flat surface. Curvature of the roof can cause leaks and induce uneven stress in the roof which may cause it to deform.  Deformation of the roof can cause water to pool along the front and back of the vent which can cause leaks.

The adapter is curved on one side the match the roof and flat on the top to accommodate the flat vent flange.

Each adapter is made to fit a specific roof curvature. Upon ordering we will reach out with instructions on how to easily measure the curvature of the roof. There is a diagram in the listing showing the method. Please make the order and then we will design the adapter. We can send a drawing of the adapter to confirm the measurements provided.  If measured properly we guarantee that the adapter will fit.
Roof Vent Adapter Install procedure:
We recommend 3m Window-weld adhesive which you can get at Napa. 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.
