How to Tie the Tensionless Hitch

 

Usage

The Tensionless Hitch is an anchor hitch primarily used in rappelling, rescue work, and general rigging. Unlike traditional knots, it preserves nearly 100% of the rope’s strength, making it one of the most efficient anchor knots available.

Why Learn the Tensionless Hitch?

This hitch provides superior strength and security by eliminating stress points found in traditional knots. It is easy to tie and untie while being highly effective for securing a loaded line to a fixed object like a tree, post, or anchor.

Common Uses

  • Rescue Operations: Securing a loaded rope to an anchor point.
  • Climbing and Rappelling: Providing a high-strength anchor for rappelling setups.
  • General Rigging: Attaching rope to smooth poles, beams, or other fixed objects.

    Notable Features

    • 100% Strength Retention: Unlike traditional knots, this hitch does not weaken the rope.
    • Non-Jamming: Easy to untie even after heavy loading.
    • Highly Secure: When wrapped sufficiently, it provides excellent grip and stability.

    Variations

    Round Turn and Two Half-Hitches vs. Tensionless Hitch

    • Round Turn and Two Half-Hitches: Easier to tie but reduces rope strength.
    • Tensionless Hitch: Preserves full rope strength and is more secure.

    Lighterman’s Hitch vs. Tensionless Hitch

    • Lighterman’s Hitch: Provides strong grip but requires alternating turns.
    • Tensionless Hitch: More straightforward to tie and does not introduce as much rotational force.

    History

    The Tensionless Hitch has been referenced in various rigging and rescue manuals. Ashley documented a similar knot in ABOK #2047, though it lacked a specific name. Today, it remains a preferred method for high-strength anchors in professional rescue and climbing communities.

    Security Level

    The Tensionless Hitch provides unparalleled security when tied around a sufficiently large anchor. Additional wraps may be required for smoother or polished surfaces.

    Downsides

    • Anchor Size Requirement: Requires an anchor at least 8x the rope diameter for optimal effectiveness.
    • Load Dependency: Will not hold without a continuous load.

    Structure

    1. Wrap the rope around a sturdy anchor 3-4 times.
    2. Tie a Figure Eight Loop at the working end.
    3. Clip a carabiner through the loop and attach it to the standing end.
    4. Ensure that there is no tension in the carabiner connection.

    Pro Tip: Ensure at least three full wraps for a secure grip, especially on smooth or polished surfaces.

    FAQ

    What is the Tensionless Hitch used for?

    It is primarily used for creating high-strength anchor points in rescue work, climbing, and rigging.

    How does it compare to other anchor hitches?

    Unlike traditional knots, it maintains full rope strength, making it ideal for high-load situations.

    Can it be untied easily?

    Yes, it remains non-jamming even after bearing heavy loads.

    Is it suitable for smooth poles or beams?

    Yes, but additional wraps should be added for better friction.

    Important Notes on Safety

    Ensure the anchor is sufficiently large and secure before applying load. Always verify proper tying technique before use in high-stakes applications.
