Horze Elastic Blanket Surcingle

This thing is not at all usable to me but I'm stuck with it, don't want to spend the money to send it back. It's extremely wide, wider than any surcingle on any of my blankets and I'm not sure how you are supposed to use this. I found another product from the company that actually made my blanket, that works.

He can be destructive and it helps to be able to find pieces to fix a blanket rather than buy a whole new one.
