has custom clip support points for awning
support riveted directly onto the fiberglass and I donít think that there is any extra inside support. Unfortunately, the prior owner removed the awning
after it was damaged beyond repair by a windstorm leaving the support points on the bottom/side and the roof mounted mounting brackets.
In lieu of the flagpole holders, I would think that bimini fittings normally used on boats might be better and less obtrusive. For example: support
. I suspect that there are different sizes which hopefully would fit your awning supports. They are also available in stainless steel.
And, yes, I would use silicone sealant when riviting/screwing the supports to your Bioler.
