I'm trying to spource nylon edge guard. This stuff is typically hard white nylon, and one edge of it looks like a castle. It is used to protect wires, etc that pass through holes in aluminum, etc. Sorry, wish I knew the correct name for it. Thanks
Have you tried your local non-big box hardware store? Mom & Pop type place? Ours has it in different sizes, it's called "flexible grommet"...at least at this place. Sorry I don't have an internet source for you.
