Figure 8 follow-through

In lead climbing and sport climbing, a "Figure 8 follow-through" is a knot used to securely tie the climbing rope to the climber's harness. It involves first tying a figure 8 knot on a bight of rope, then threading the free end of the rope through the harness's tie-in points, and finally retracing the original figure 8 knot with the free end. This knot is widely used because it is simple, strong, and easy to inspect for proper tying.

Examples

In lead climbing and sports climbing, the "Figure 8 follow-through" is essential for safety. A climber uses this knot to tie their harness to the climbing rope. The process involves first forming a simple figure 8 knot on a bight (a loop in the rope). Then, the climber threads the free end of the rope through the tie-in points on their harness. After this, the climber follows the original figure 8 path with the free rope end, creating a second, intertwined figure 8 knot. The knot is snugged up tightly for security. In both lead climbing and sports climbing, the Figure 8 follow-through knot is highly valued for its reliability and ease of inspection. Climbers often double-check this knot before climbing to ensure it is tied correctly.
