Have you seen these?

Hi. I'm new here. I have gotten alot of great info and now I may have something to contribute. I was looking for a bungie cord that I could attach to a Petzl basic that my kids use with a footloop. I want it to advance automatically. I came across these at Home Depot. Pretty nice. They had a 2' and a 4'. If they don't work I can always use another bungie. The biners are molded into the ends.
