It was apparantly intended for '84-up Westfalias and weekenders, which have
a heater conduit directly above the sliding door, although a number of
people have purchased them for earlier campers and non-Westies and fit them
anyway.  It snaps on just like the rear hatch screen on a Westy, and snap
recepticles are included.  There is a double sided zipper in the middle so
you can enter/exit the van with the screen in place. You also open/close the
sliding door while it is installed, if desired.  It is available in brown or
gray trim, for $89, on my website. This item was an immediate hit when I
introducted it this summer, and many people had to wait several weeks to get
one because demand far exceeded supply. Now that the initial demand has
subsided, I finally have a couple in stock for immediate delivery, the first
time I've been able to catch up with demand since introducing them.
