                           eye splice                          double braid Class I

  Class I ropes are made from any or all of the following fibers: olefin, polyester, or nylon.                                             Additional rope needed for splice:

  to protect the rope, especially when it is to be attached to a shackle, chain or wire rope.

                or marlin spike, spread the cover strands to expose core. First pry, then pull the core
                completely out of cover from X to the taped end of the rope. Put one layer only of tape

                To assure correct positioning of Mark 1 do the following:
                Holding the exposed core, slide cover as far back as possible                                                          R

                back from the slipknot toward the taped end. Smooth again                                                                                                 1 layer of tape

                Again slide the cover toward the slipknot to expose more
                core. From Mark 1, measure along the core toward X
                a distance equal to the short section of a tubular fid
                (two short sections if using a wire fid) and make two

                      Note the nature of the cover braid. It is made up of
                      strands with either one, two or three ends. By inspec-

                      the cover, count eight (8) consecutive strands (single or
                      pairs) which revolve to the right (or left). Mark the eighth

                      around the cover. Starting at T and working toward the

                     the taped cover. For those ropes with a 20 strand cover, count and mark the fifth (5th) right and
                     left strand. From that mark count to the fourth (4th) right and left strand. Proceed in this manner,
                     marking the fifth (5th) right and left strand and then marking the fourth (4th) right and left strand,

                      cut and pull them completely out (Fig. 6A). Cut and remove next marked strands and continue with each right and left
                      marked strands until you reach point T. Do not cut beyond this point.
                      The result should be a gradual taper ending in a point. Very carefully pull the cover back through the core until point T

                     reinserting core into cover
                  From X on the cover, measure approximately one-third (1/3) a tubular fid length
                  toward the slip knot on the rope and mark this as Z.
                  You are now ready to put the core back into the cover from T to Z. Insert the fid
                  at T, jam the taped core end tightly into the end of the fid. With the pusher, push
                  the fid and core through the cover tunnel, past X and through the cover at Z.
                  When pushing the fid past X to Z, make sure the fid does not catch any internal
                  core strands.

                  note: Depending on the eye size, a fid may
                  not be long enough to reach from T to Z in one                                                                           Insert core into

                  pull the core through and reinsert the fid into
                  exactly the same hole it came out of. Do this
                  as many times as needed to reach Z.                                                                                       T

                      Hold the rope at the slipknot and with the other hand milk the cover toward the splice,
                      gently at first, them more firmly. The cover will slide over Mark 3, Mark 2 and crossover

                      reduced volume tail catching in the throat of the splice).
                      If bunching occurs at the crossover preventing full burying, smooth cover from T to X.
                      Grasp crossover at T with one hand and then firmly smooth cover slack (female side
                      of eye) with the other hand toward the throat (X).

                       A. Anchor the loop of the slipknot by tying it to a stationary object before starting to
                       bury. You can then use both hands and the weight of your body to more easily bury
                       the cover over the core and crossover (see Figure 1 and Figure 2).
                       B. Holding the crossover tightly, milk all the excess cover from R to X.
                       Flex and loosen the rope at the crossover point during the final burying process.
                       Hammering the cover at X will help loosen the strands.
                       With larger ropes it is helpful to securely anchor the slipknot, attach a small line
                       to the braided core at the crossover and mechanically apply tension with either a
                       block and tackle, capstan, come-a-long, or power winch.
                       Tension will reduce the diameter of the core and
                       crossover for easier burying (see Figure 2).

                       lock-stitching the eye.
