That’s a Kreh loop knot, commonly used when fishing.
Actually, I think it’s a noose, with the tag end coming up the top. A Kreh Loop has the tag end coming out the bottom.
The difference determines if it’s a slip knot or not. A noose is a slip knot and would make a poor garage door pull. A Kreh Loop would be a better choice because it retains it’s size.
But apart from the “noose” or “Kreh” question, the real question is: Is this a rope configured to send a message of race hatred to Bubba Wallace? And I’d bet $1000 that it is not related to Bubba in the slightest.
Same knot I’ve been tying most my life, I use 5 loops. I use it for tying on hooks, crank baits, worm’s and spinners. Fresh or salt water.
