How to Tie the Tensionless Hitch (With a Carabiner)

 

Usage

The Tensionless Hitch is one of the strongest anchors possible. Unlike traditional knots, which weaken the rope’s strength to some degree, the Tensionless Hitch preserves nearly 100% of the rope’s integrity. This makes it widely used in rappelling, rescue work, and general rigging.

Why Learn the Tensionless Hitch?

• Provides superior strength and security by eliminating stress points found in traditional knots.
• Easy to tie and untie, even under heavy loads.
• 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 in high-angle rescue scenarios.
• Climbing and Rappelling: Creating 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

• Tensionless Hitch with Carabiner vs. Tensionless Hitch with Two Half-Hitches:
• Carabiner Method: Quick to set up and release, reduces rope wear, but relies on the strength of the carabiner.
• Two Half-Hitches Method: More secure under dynamic loads, doesn’t require hardware but can be harder to untie under heavy loads.

Similar Knots

Round Turn and Two Half-Hitches vs. Tensionless Hitch

• Pros: Easy to tie and widely used.
• Cons: Reduces rope strength compared to the Tensionless Hitch.

Timber Hitch vs. Tensionless Hitch

• Pros: Works better for wrapping around logs and pulling in-line rather than perpendicular.
• Cons: Not as easy to tie or reliable.

History

The origins of the Tensionless Hitch can be traced back to maritime practices, where similar techniques were employed to secure vessels without compromising rope integrity. It was documented by American sailor Clifford Warren Ashley in his 1944 publication, The Ashley Book of Knots (ABOK #2047), though it lacked a specific name at the time. Over the years, the hitch has been widely adopted in climbing, caving, and rescue operations due to its simplicity and effectiveness.

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. It can be made slightly more secure by using the carabiner method, although the half-hitches are generally great for most applications.

Downsides

• Requires a large anchor: Must be at least 8x the rope diameter for optimal effectiveness.
• Will not hold without continuous load: The tension must remain constant for the hitch to be effective.

Structure (Step-by-Step Instructions)

1. Wrap the rope around a sturdy anchor at least 5 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.

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.
• Wrap a minimum of 5 times for maximum friction and security.
• The tag end should have no tension or pull when you're done.
• Always verify proper tying technique before use in high-stakes applications.
