Pending adapter matches the contour of the OEM roof so an 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.

The 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". They are a generic size and will need to be cut to length. These strips are not contoured to the van corrugations.

adapter. Then press the adapter down onto the roof until the adhesive

surface area. Using the adhesive that oozes out, make a fillet around
the adapter with a double gloved finger. Pull the tape within 15
