Thanks Gray Climber - there are lots of names for lots of knots, Ashley's and Grog are great resources.
Thanks for watching our video.

Our Safe D carabiner is rated at 11kN (2470lbs) in the cross section loading, over 8:1 safety margin for a 300lb load. This technique is acceptable for emergency use applications only--like a fast escape from a burning building. The preferred method when time allows would be to wrap multiple times then clip back to the rope for a full strength tie off.
