O ok, I thought I was drifting off.
Yea, I guess any type 1/4 inch rope will work really. A hardware store or home supply store should have rope. You just have to bring in the old gasket and pick the closest match. If ya get a match let me know cause all mine need a better match than what I have, or what I'm using as door gaskets now. Just seems the original gaskets had a tighter weave in the rope, I can't find that today.
Ya know how there's the pool noodles, those long foam things you float around on in the pool. I bet you could get away with 1/4 inch pool noodles as gaskets
