Pending adapter matches the contour of the OEM roof so an air
conditioner mounts to a flat surface. Prevents distorting the roof
metal and can be used as an aid for locating the AC.
They are CNC machined out of UV and fire
resistant expanded PVC.
framing strips are expanded PVC and bonded to the interior roof with a thick
bead of Windo weld. They are more flexible than wood and plenty strong to
support the AC 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".
If you order the framing strips they will come in a separate box.
will be 6 strips. 2 for each side running along side the hole and 2 that can be cut to frame the for and aft sides of the hole.They are a generic size and will need to be cut to length. These strips are not contoured to the van corrugations.
Adapter Install procedure:
We recommend 3m Window-weld adhesive which you can get at Napa. 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.
