Which knot is typically tied at the end of a rope to indicate the end for rappelling?

The stopper knot is specifically designed to prevent the end of a rope from slipping through a device or past an anchor point, making it crucial for activities like rappelling. When the end of the rope is secured with a stopper knot, it creates a barrier that indicates where the usable length of the rope ends, ensuring that the user can safely rappel without the risk of slipping off the end.

In rappelling situations, it's essential to have a clear and secure indication of the rope's end to prevent accidents. Other knots, while useful in various contexts, do not fulfill this specific function with the same reliability as the stopper knot. This knot is easy to tie, secure, and readily visible, reinforcing its importance in safe rope management.
