What is a figure-eight stopper knot used for?

• A. To prevent a rope from slipping through a hole or device and to stop the rope end.
• B. To create a fixed loop at rope end.
• C. To join two ropes.
• D. To create an adjustable loop.

Answer: (A)

The figure-eight stopper knot is all about making a secure end stop for the rope. Its shape creates a noticeable bulge at the end that catches on holes, carabiners, or other hardware, so the rope can’t slip back through and the end won’t unravel. It holds up under load and is relatively easy to untie after being loaded, which is why it’s a reliable choice for preventing pass-through.

It’s not used to form a fixed loop at the rope end, to join two ropes, or to create an adjustable loop—those tasks are accomplished with other knots designed specifically for those functions.
