Which knot is commonly used as a stopper knot to prevent slipping?

• A. Bowline
• B. Reef knot
• C. Figure-eight stopper knot
• D. Clove hitch

Answer: (C)

Stopper knots are tied at the end of a rope to keep the end from slipping back through a hole, loop, or device. The figure-eight stopper knot creates a large, solid bulge that cannot pass through openings and stays secure under load, yet remains relatively easy to untie after being loaded. This makes it a dependable end stopper. The other knots don’t serve this purpose as well. A bowline forms a fixed loop and isn’t designed to behave as an end stopper; it can loosen or become difficult to untie after heavy loading. The reef knot (square knot) tends to capsize or slip under tension, which defeats the purpose of an end stopper. A clove hitch is intended for securing to a post or object and can slip or shift with movement, so it’s not reliable as a stopper at the rope’s end. So, the figure-eight stopper knot is the best choice for preventing slipping.
