Thanks for the quick reply, but it’s going to be tricky. It’s an articulated piece which 4 poles connect to, its not just a mater of finding a similar length/width pole sadly. That said it might be possible to use another brand. Does anyone know what brands use a similar construction?
I suspect that most brands don't manufacture their own poles (or canvasses.) I suspect they buy them in from a third party, so the chances are another brand will use the same ones.
I would take a photo of the broken pole - some close-upos etc - and email it to some caravan/awning dealers. You never know....
