The OEM grab loop inside my '84's sliding door finally came apart last year. I replaced it with one I found online somewhere. Unlike the OEM loop, which had a core of what looked like cotton cord, the replacement has no such core and it's stretchy. It parted this morning, nearly sending me tumbling, so I need to find a proper one to replace it. Who sells the good ones?
