Learn To Tie The Midline Splice

Learn to tie the midline splice.

Tying a 3-strand midline splice in a rope involves creating a secure and neat connection between three strands. Here’s a simplified step-by-step guide:

Materials Needed:

  • 3-strand rope
  • Tape (optional)
  • Sharp knife or rope cutter
  • Measuring tape (optional)


  1. Prepare the Rope Ends:

    • Unlay (untwist) the ends of the rope for a few inches to expose the individual strands.
    • If desired, you can tape the ends to prevent fraying.
  2. Unlay the Middle Section:

    • In the middle of the rope, unlay a section of the strands to expose their core.
    • The length of this section will depend on the desired length of your splice. A common rule of thumb is 30 times the rope’s diameter.
  3. Interlock the Strands:

    • Take one strand from each end (1 from each side of the unlayed section) and the central core strand.
    • Gently unlay these three strands and interlock them, ensuring they are aligned smoothly.
  4. Begin the Splicing Process:

    • Gradually twist and tuck the interlocked strands back into the unlayed section of the rope’s core.
    • Maintain a consistent tension to create a smooth and even splice.
  5. Continue Splicing:

    • Keep working the splice, gently pushing and tucking the interlocked strands further into the core.
    • Ensure that the splice maintains an even diameter along its length.
  6. Trim Excess Strands:

    • Once the splice is complete, trim any excess strands protruding from the splice.
  7. Tighten and Test:

    • Carefully tighten the splice to remove any slack, ensuring it’s snug and secure.
    • Test the strength of the splice by applying gradual tension; it should hold firmly.
  8. Finishing Touches:

    • If desired, you can use heat to melt the rope ends slightly, preventing them from fraying.

Remember, practicing this technique is essential to achieving a clean and secure midline splice. The actual process may vary based on rope type, thickness, and personal preferences. Always prioritize safety and test the splice’s strength before relying on it in critical situations. This is the best way to learn to tie the midline splice.
