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://www.ebay.com/itm/143604536736
Don't
be fooled by the lower priced copy cat adapters here on Ebay. We have
seen some of them and they are junk! They are not made out of the high
quality material that we use.
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.
This backing frame may come in a "Grey" color.
Instructions for use: bond this frame to the inside of the roof
skin with 3M Windoweld(TM) or 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.
