I have a 9ft. Offset patio umbrella that the plastic piece that slides up and down the pole when adjusting position to put umbrella in when opened, is cracked. I'm not sure, but I think the part is called a support collar.
I've tried glueing it, with no luck. I've not been able to find a replacement part. Is there a way to fix the piece or a place I can buy a replacement part?
Thanks.
