Dress the knot by
                                    incrementally adjusting
                                    all the rope strands. Be
                                    sure that all strands
                                    are parallel within the
                                    knot, the tail is 6 inches
                                    (no longer or shorter),
                                    and there is a small gap
                                    between the knot and the
                                    harness.







               The Figure 8 Follow Through

              Strength: Reduces rope strength by 10-20 percent.
              Visual clarity:  When tied correctly and well
              dressed, the figure 8 follow through is unmistak-
              able; its curving parallel lines create a symmetry
              that no other knot possesses.
              Efficiency: It takes only three steps to tie the
              figure 8 follow through, and it is relatively easy to
              untie unless it has been heavily loaded.
              Security: The figure 8 follow through is a very
              secure knot. It would require two unlikely contor-
              tions to reduce the load-bearing properties of the
              knot; therefore no secondary knots or hitches are
              required to secure the figure 8 follow through.
              Failure mechanism:  The figure 8 follow
              through has a consistent failure mechanism when
              large forces are applied to it. It breaks just inside
              the second turn of its follow through.
              Ideal applications: Climbing in a group.
              Climbing with novices. Climbing instruction.
