Awning Saver
Our caravan awning was starting to show the signs of being out in the weather for 10 years. With the Awning Saver installed it is hoped that we might postpone the inevitable replacement for a little longer. The Awning Saver was easily installed and gives some peace of mind that the awning is less likely to separate from the caravan at the point of attachment.
