The KEY strip (I will call it "key" for less typing) attaches the ZD (ZipDee) to the roof of the trailer. Rather than having a metal to metal hinge or other type of mount/attachment/key that will be noisy and be prone to leak and possible cause of stress on Airstream shell, ZD uses a high quality fabric for the key.
These are exposed to all the roof nastiness.. heat, rain, snow...birds, etc.. so eventually it fails. That causes the ZD to become detached from the Airstream with unpredictable results.
Our Airstream is a 1999.... so... 18 years of service..
There are 2 basic widths... the smaller for the small awnings and larger for big ones. ZD will walk you thru the process of determining the width and length for your AS.
