The construction of a harness knot consists of one half hitch and one crossing hitch made by each of the two joined ropes around the other rope’s body.

The process of tying a harness knot might seem complicated at first, but with practice, it can quickly become a valuable skill. This beneficial knot can also be found in several different applications like securing climbing ropes, creating anchor points, or making primary knot connections. Given the range of situations where a harness knot can be used, it’s no surprise that it is considered an essential knot to learn for outdoor enthusiasts and climbers.

When learning how to tie a harness knot, it’s crucial to pay attention to the specific steps, such as creating an overhand loop with the rope under tension and using a half hitch with the second rope around the standing part of the first rope. By following these instructional guidelines, even beginners can master the harness knot and use it efficiently in a variety of situations.

Basic Concepts

Knot Terminology

Knot terminology is essential for understanding the different components involved in tying and using knots. Some common knot-related terms include:

  • Tie: The act of connecting two ropes or sections of rope using a knot.
  • Loop: A circular or oval shape formed by the rope when it’s doubled back on itself.
  • Bight: When a section of rope is bent or folded, without crossing over itself.
  • Hitch: A type of knot used to attach a rope to an object, such as a post or a ring.
  • Bend: A knot used for joining two ropes together.
  • Tension: The force that’s exerted on a rope, often to keep a knot tight and secure.
  • Slack: The opposite of tension, referring to a rope that is without tension or is loose.

Types of Knots

There are various types of knots used in different applications, such as climbing, sailing, and rescue operations. Three main categories of knots include:

  1. Harness Knots: These knots are used to create a secure loop around a person or object for lifting or safety purposes. An example of a harness knot is the Hasty Harness Knot, which is suitable for constructing a temporary lifting harness seat.
  2. Climbing Knots: These knots are essential for climbers to secure ropes to themselves, other climbers, or anchors. Fundamental climbing knots include the Figure 8 Knot (Rewoven Figure 8 Knot/Figure 8 Follow Through Knot) which is used for securing the rope to a harness.
  3. Utility Knots: Everyday knots used for various purposes such as tying objects together, creating loops, or fastening items. Examples of utility knots are the Square Knot for joining two ends of a rope, and the Bowline Knot for making a secure loop at the end of a rope.

Understanding knot terminology and the different types of knots is crucial for selecting the right knot for a specific task. It is essential to practice and master the knots relevant to your needs for safety and effectiveness.

Harness Knot Characteristics


A harness knot is a reliable and practical knot that features a combination of a half hitch and a crossing hitch, made by two interlaced ropes around each other’s body, with the ends caught in between at the elliptical eye in the center (source). The structure of this knot provides a relatively secure grip, ensuring that it will remain intact under tension.

Applications and Uses

  • Climbing: Harness knots are utilized in various climbing tasks, such as securing ropes to harnesses, rappelling, and building anchors. The strength and dependability of this knot make it suitable for these essential activities (source).
  • Towing: The harness knot is often used by sailors for making knots in towlines, as it can be tied and untied easily, while also maintaining the rope’s strength. The knot’s ability to withstand tension without slipping is particularly advantageous in these situations (source).

Tying Instructions

  1. Create an overhand loop with the rope under tension.
  2. Feed the working end of the second rope through the loop and over the standing part of the first rope.
  3. Pinch the loop down while keeping tension on the standing part of the first rope.
  4. Tie a half hitch with the working end of the second rope around the standing part of the first rope, further securing the knot.
  5. Tighten the knot to ensure security (source).

With these characteristics, the harness knot is widely recognized for its utility and reliability in various applications, such as climbing and towing. Its ability to hold under tension and easy-to-tie nature makes it an essential knot for both expert climbers and beginners alike.

Step-By-Step Guide

  1. Begin by creating an overhand knot in the end of the rope you wish to secure onto your harness.
  2. Attach the rope to your harness with a locking carabiner and ensure it is properly secured.
  3. For additional security, use another piece of rope or webbing to tie a bowline knot around your waist.
  4. Attach this loop to the carabiner on your harness.

Common Mistakes

  • Forgetting to lock the carabiner: Always make sure the locking mechanism on your carabiner is properly engaged to avoid any accidents.
  • Not tightening the knots: Ensure that the overhand knot and bowline knot are pulled tight for maximum security.
  • Using worn or damaged ropes, carabiners, or webbing: Regularly inspect your equipment for signs of wear, and replace as necessary.


  • If the overhand knot becomes difficult to untie after use, try wetting the rope or using a horse to gently apply pressure on either side of the knot.
  • If the bowline doesn’t hold its shape, make sure that the crossing turns of the knot are correctly positioned, and that the tail end of the rope is on the outside of the loop.
  • In case your carabiner becomes stuck or jammed, ensure that debris or dirt is not causing the problem, and consider using a specialized carabiner cleaning tool.

Remember, always practice caution and safety when working with harness knots and other climbing equipment.

Different Types of Climbing Knots

Climbing involves various techniques and equipment, with knots being a critical component. There are several types of knots used in rock climbing, providing different functions and levels of security. This section highlights three essential climbing knots: the Figure-Eight Knot, the Clove Hitch, and the Munter Hitch.

Figure-Eight Knot

The Figure-Eight Knot is one of the most popular and fundamental knots in rock climbing. The knot gets its name from its resemblance to the number 8 when tied. It is often used for:

  • Attaching a rope to a harness
  • Creating a stopper knot at the end of the rope
  • Joining two ropes together for rappelling

The Figure-Eight Knot is known for being:

  • Easy to tie and untie, even when loaded
  • Highly visible and identifiable
  • Strong and reliable

To tie a Figure-Eight Knot, follow these steps:

  1. Create a loop in the rope, crossing the working end over the standing part
  2. Pass the working end back through the loop
  3. Adjust and tighten the knot as needed

Clove Hitch

The Clove Hitch is a versatile and adjustable knot used to:

  • Secure a rope to a carabiner
  • Attach a rope to a fixed anchor point
  • Create friction for setting up anchors and belays

The key features of a Clove Hitch include:

  • Easy to tie, adjust, and untie
  • Strong and secure when under load
  • Can be tied with one hand

To tie a Clove Hitch, follow these steps:

  1. Pass the rope over the object (e.g., a carabiner)
  2. Cross the working end over the standing part
  3. Pass the working end back over the object in the original direction
  4. Tuck the working end under the new loop created and tighten the knot

Munter Hitch

The Munter Hitch is a friction hitch used for:

  • Belaying a climber
  • Rappelling
  • Lowering loads

The Munter Hitch has some unique attributes:

  • Creates a high level of friction
  • Can be used with a locking carabiner for added security
  • Reversible, allowing for easy load transfer in rescue situations

To tie a Munter Hitch, follow these steps:

  1. Form a loop in the rope with the working end on top
  2. Fold the loop back onto itself, creating a second loop
  3. Clip a locking carabiner through both loops
  4. Lock the carabiner and adjust the rope as needed

Anchor System Knots

Anchor system knots are fundamental for climbers to ensure safety and efficiency when climbing or rappelling. In this section, we will explore three essential knots used in anchor systems: the Prusik Knot, the Klemheist Knot, and the Water Knot.

Prusik Knot

The Prusik Knot is a versatile friction hitch that can be used for multiple purposes in climbing and rappelling. It can be employed as a self-rescue knot, a progress capture device, or for ascending a fixed rope. To tie a Prusik Knot, you will need a loop of cord or a sling. Wrap the loop around the main rope a few times, making sure the wraps are even and snug. Then, pull the ends of the loop through the middle to create the hitch. Adjust the knot as necessary to ensure it can grip the main rope effectively when weight is applied and slide smoothly when not under load.

Klemheist Knot

The Klemheist Knot is another friction hitch knot that can be used for ascending ropes or as a backup knot while rappelling. It is similar to the Prusik Knot, but with some differences in the tying process. To tie a Klemheist Knot, begin with a loop of cord or a sling and wrap it around the main rope. However, instead of wrapping evenly as with the Prusik Knot, start at one end of the loop and wrap towards the other end, creating a series of wraps that spiral around the main rope. Once the wraps are complete, tuck the end of the loop through the beginning wrap and pull tight.

The Klemheist Knot is considered to be easier to untie after being loaded compared to the Prusik Knot. However, it is directional, meaning it can only provide friction in one direction, while the Prusik Knot works in both directions.

Water Knot

The Water Knot is a simple, yet strong knot that is primarily used for joining two pieces of webbing together, such as creating a sling or joining the ends of a runner. It is also known as the Tape Knot or Ring Bend. To tie a Water Knot, start by tying an overhand knot in one end of the webbing. Then, take the opposite end and follow the path of the overhand knot in reverse, essentially retracing the original knot. Ensure that the two strands of webbing lay parallel and snug within the knot, and leave at least a 3-inch tail on each end for safety. The Water Knot should be checked regularly for slippage, as it can loosen over time if not adequately tightened.

Joining and Rope Management Knots

When climbing, it’s essential to know the proper knots and techniques for joining ropes and managing them effectively. In this section, we’ll focus on three specific knots: the Double Fisherman’s Knot, Double Bowline, and Ring Bend.

Double Fisherman’s Knot

The Double Fisherman’s Knot is a reliable and strong knot used to connect two ropes of equal or similar diameter. It’s widely used in climbing activities and ideal for joining rappel ropes or creating a closed loop of cord for anchors. To tie a Double Fisherman’s Knot:

  1. Hold the two rope ends parallel to each other, with some overlap.
  2. With one end, make a loop around the other rope, then wrap it around both ropes twice, going towards the loop.
  3. Tuck the end through the loop and tighten the knot.
  4. Repeat steps 2 and 3 with the other rope end in the opposite direction.
  5. Pull the two knots together to complete the Double Fisherman’s Knot.

Double Bowline

The Double Bowline is an alternative to the figure-eight knot for tying into a harness. It’s easier to untie after being subjected to heavy loads and offers a secure attachment point for the climber. To tie a Double Bowline:

  1. Form a loop with the rope, making sure the working end is on top.
  2. Thread the working end through the loop from the bottom.
  3. Bring the end around the standing part and then back down through the loop.
  4. Repeat steps 2 and 3, essentially forming two loops inside the first loop.
  5. Tighten the knot and ensure a tail length of at least six inches.

Ring Bend

A Ring Bend, also known as a Water Knot or Tape Knot, is commonly used to join two flat straps of webbing to create a closed loop for slings or anchors. It can also be used to join ropes of equal diameter. To tie a Ring Bend:

  1. Tie an overhand knot in one end of the webbing or rope.
  2. Thread the other end through the overhand knot following the same path in the opposite direction.
  3. Tighten both knots while maintaining equal distance between them.

These knots are fundamental tools for climbers to effectively manage and join ropes during their adventures. Familiarize yourself with them and practice regularly to ensure your safety on various climbing terrains.

Specialized Knots and Techniques

Man-Harness Knot

The Man-Harness knot is a practical and efficient knot used for hauling or dragging objects using a rope. This knot can be tied in the bight of a rope, creating a secure loop that can be slipped onto a person’s shoulder or waist for carrying. It is important to note that the Man-Harness knot can tighten under load, so it’s advisable to use a stopper knot to prevent it from slipping or becoming too difficult to untie.

To tie the Man-Harness knot, make a loop in the rope and then pass another loop through the first one. Tighten the knot by pulling on the standing part and the free end of the rope, making sure that the loop remains relatively flat for maximum stability.

Girth Hitch for Webbing Strap

A Girth Hitch is a versatile and quick knot to attach a webbing strap to an anchor point, such as a tree or a carabiner. To tie this knot, first form a loop by folding the webbing strap in half and passing the folded end through the anchor point. Next, pull the other end of the strap through the loop created by the folded strap. Finally, tighten the knot securely by pulling on both ends of the webbing strap.

This hitch is ideal for attaching gear, such as a climbing harness, to a fixed point, allowing for quick and easy adjustments to accommodate various loads and situations. However, it’s essential to keep in mind that Girth Hitches can slip under certain circumstances and may not be suitable for critical or heavy loads without additional backup knots.

Stopper Knot

Stopper knots are essential for preventing ropes or cords from unraveling or sliding through other knots when tension is applied. Common stopper knots include the Overhand Knot and the Figure Eight Knot, which can be tied at the end of a rope, keeping it secure and preventing it from slipping.

To tie an Overhand Stopper Knot, create a loop near the end of the rope, and then pass the tail of the rope through the loop. Pull tight to secure. For the Figure Eight Stopper Knot, make a loop in the rope, then twist the loop once more, forming a figure-eight shape. Pass the tail of the rope through the top of the figure-eight and pull tight.

These knots are often used in conjunction with other knots, such as the Man-Harness Knot or Girth Hitch, to ensure that the rope or webbing straps remain securely fixed in place during use.

Safety and Best Practices

Choosing the Right Knot

When it comes to climbing and safety, selecting the right knot is essential. Among the various options, the harness knot stands out as a reliable and secure choice for attaching ropes to harnesses or other objects. Harness knots are often used in tandem with other knots, such as prusik loops or corder knots, to enhance their efficiency in different climbing situations.

One crucial factor when choosing a suitable knot is understanding the different load directions that the knot will encounter. For instance, if the load direction changes during a climb or rescue operation, it’s essential to choose a knot that maintains its strength and stability in all directions.

Inspecting and Maintaining Knots

It’s vital to regularly inspect and maintain the knots you use in any climbing or safety situation. Proper inspection ensures that your knots remain in good condition and are not compromised by wear and tear or other environmental factors.

First, always double-check your knots before starting any climbing activity. Ensure that they are tied correctly and securely, with no visible signs of wear or damage. When using an overhand loop, for example, examine the loop for any fraying or damage that might have occurred from previous use.

Routine maintenance of knots includes:

  • Re-tying knots that appear loose or worn out
  • Replacing ropes or cords with signs of fraying or excessive wear
  • Periodically practicing knot-tying skills to reinforce your ability

By following these safety and best practices, you can ensure that your use of harness knots or any other knot will contribute to a safer and more enjoyable climbing experience. Keep in mind the importance of choosing the right knot for your specific situation and always inspect and maintain your knots to guarantee their effectiveness and reliability.
