Hi, Thanks for your message and offer of help with the awning riser. I am unsure what I need as it is missing.....It needs to fit with a spike into the awning rail at the centre mounting point. I guess this also has a means of securing it upright unless it is a very tight fit in the mounting point bracket. The other, upper-most end, will need to take the hook from the end of the ridge pole coming up to the van, I guess that this could be a spike. Either way the riser needs to be adjustible for height I think.
Perhaps other Folk will know about these things but I have never seen one.
Hope you CAN help. Best regards. Graham
