Stopper Knot

A stopper knot is a type of knot used in climbing to prevent the rope from running through a belay device or anchor. Commonly tied at the end of a climber's harness, it ensures added safety by acting as a backup in case the primary knot fails. Typically, an overhand knot or figure-eight knot is used for this purpose.

Examples

In lead climbing, a stopper knot serves as a crucial safety measure. Climbers tie it at the end of their rope to prevent it from accidentally slipping through the belay device, which could cause a fall. It's particularly important during lead climbs where rope length and proper management are key. In sports climbing, a stopper knot is often used when the climber ties into the harness. It acts as a backup knot, securing the primary knot, usually a figure-eight, to ensure it doesn't come undone. This additional precaution is essential for maintaining safety throughout the ascent and during belaying.
