Loop to Loop Knot: Step-by-Step Guide & Expert Tips

The loop-to-loop knot is a commonly used fishing knot that allows you to quickly attach or detach a leader (tippet) to a fly line.

It’s a reliable and straightforward knot that provides a strong connection. Here’s how to tie the loop-to-loop knot:

  • Form a loop on the end of the fly line.
  • Take the end of the leader or tippet and pass it through the loop from the front.
  • Make a second loop with the leader or tippet by returning the end and passing it through the first loop from behind.
  • Moisten the lines with water or saliva to lubricate them.
  • Hold both standing lines (the fly line and the leader/tippet) in one hand and the loops in the other.
  • Pull the standing lines (fly line and leader) away from each other to tighten the knot.
  • Trim the tag ends if necessary, leaving a small amount of line for added security.

Now, you have a loop-to-loop connection between your fly line and leader/tippet.

To remove the leader, reverse the process by pulling the loops apart, and you can easily attach a new leader using the same knot. 

This is especially useful to quickly change leaders with different lengths or strengths without doubting knots.

Best loop to loop knots

The loop-to-loop knots are versatile and commonly used in various fishing scenarios. 

Here are some of the best loop-to-loop knots for specific fishing setups:

Perfection Loop to Perfection Loop: This simple, strong, loop-to-loop connection works well for attaching a leader or tippet to a fly line. 

It’s easy to tie and connects smoothly through the rod guides.

Double Surgeon’s Loop to Double Surgeon’s Loop: The Double Surgeon’s Loop is a quick and reliable knot for creating loops on the end of the fly line and leader. 

It forms a strong loop-to-loop connection suitable for most fly fishing situations.

Bimini Twist to Perfection Loop: The Bimini Twist creates a strong, non-slip loop at the end of the leader.

By attaching this loop to the fly line’s loop using a Perfection Loop, you get an incredibly strong loop-to-loop connection, which is especially useful for big game fishing or saltwater applications.

Spider Hitch to Double Surgeon’s Loop: The Spider Hitch creates a doubled loop at the end of the leader, providing additional strength. 

Connecting to the fly line’s loop using a Double Surgeon’s Loop forms a secure loop-to-loop connection ideal for heavy-duty fishing scenarios.

Albright Knot to Perfection Loop: The Albright Knot is commonly used for connecting different lines of varying diameters. 

Combined with a Perfection Loop, it creates a reliable loop-to-loop connection, particularly for attaching a heavy fluorocarbon or monofilament leader to a fly line.

Remember to moisten the lines before tightening any loop-to-loop connection, as this reduces friction and helps ensure a stronger knot. 

The best knot for you depends on the fishing situation, the type of line you use, and personal preference.

 It’s always a good idea to practice tying these knots and test their strength before using them in actual fishing situations.

Perfection loop knot

Perfection loop

The Perfection Loop is a popular and straightforward knot that creates a strong and reliable loop at the end of a leader or tippet. 

A loop-to-loop connection is commonly used in fly fishing to attach flies, tippets, or leaders to the fly line. Here’s how to tie the Perfection Loop knot:

Step-by-Step Guide to Tying the Perfection Loop Knot:

  • Take the end of the leader or tippet and form a small loop. 
  • On the other hand, take the tag end (the free end) of the leader or tippet and pass it through the loop from the front (the side facing you).
  • Hold the tag end and the standing line (the part of the leader/tippet attached to the spool) together with one hand.
  • With the same hand, create a larger loop by bringing the tag end around and passing it through the original loop from behind (the side facing away from you).
  • At this point, you should have two loops side by side, with the larger loop encompassing the smaller loop.
  • Moisten the loops with water or saliva to lubricate the knot and reduce friction during tightening.
  • Hold the larger loop with one hand and the tag end and standing line with the other hand.
  • Carefully pull all four ends to tighten the knot. Make sure the wraps cinch down smoothly to avoid any crossing of the lines.
  • Once the knot is tightened, trim the leader’s tag end (the free end) or tippet to the desired length.

Your Perfection Loop knot is now complete. You can use this loop to attach your flies, tippets, or leaders to the fly line using a loop-to-loop connection. 

The Perfection Loop is strong, reliable, and retains nearly 100% of the line’s original strength when tied correctly, making it an excellent choice for fly fishing applications.

Loop to loop fly line to leader

Loop-to-loop connection between a fly line and a leader is one of the most common and convenient ways to attach them.

 The loop on the fly line is typically pre-installed, and you can easily create a loop on the leader to match. Here’s how to make the loop-to-loop connection:

Fly Line Loop

Fly Line Loop

Most modern fly lines come with a small loop at the end. You can skip this step if your fly line already has a loop. 

If it doesn’t have a loop, you can create one using the following method:

  • Double over the end of the fly line to form a small loop.
  • Hold the doubled line so the loop is formed.
  • Use fly line backing or monofilament to make five to seven wraps around the doubled line and the fly line itself.
  •  Thread the tag end of the backing/monofilament through the loop near the end of the fly line.
  •  Moisten the line and pull both ends of the backing/monofilament to tighten the wraps.
  •  Trim the tag end of the backing/monofilament close to the wraps.

Leader Loop

You can add a loop to the end of your leader using one of the following knots:

  • Perfection Loop: This is the most common knot used to create a loop in the leader. It’s simple to tie and forms a strong loop.
  • Double Surgeon’s Loop: Another easy-to-tie loop knot attaches the leader to the fly line.

Once you have the loop at the end of your leader, you’re ready to connect it to the loop on the fly line.

Connecting the Loops

Connecting the Loops
  • Pass the leader’s loop through the fly line’s loop from the front (the side facing the fly rod).
  • Then, pass the leader’s loop back over the fly line’s loop from the back (the side facing away from the rod).
  •  Moisten the loops with water or saliva to lubricate them.
  • Hold the standing lines (the fly line and the leader) in one hand and the loops in the other.
  • Pull the standing lines (fly line and leader) away from each other to tighten the knot.
  • Trim the tag ends if necessary, leaving a small amount of line for added security.

The loop-to-loop connection allows for a quick and easy way to change leaders or attach different types of leaders to match various fishing conditions without re-tie knots. 

It’s a reliable connection; with practice, you can tie it quickly, even in low-light or adverse weather conditions.

Benefits of the loop-to-loop knot 

Convenience: It enables you to change leaders or tippets easily without re-tie knots, saving time and hassle on the water.

Versatility: The loop-to-loop connection works with various line types, including fly lines, leaders, and tippets, allowing you to adapt to different fishing conditions and species.

Strength: When tied properly, the loop-to-loop knot is strong and reliable, ensuring that your leader-to-line connection can withstand the pressure of casting, setting the hook, and battling fish.

Consistency: With practice, you can tie the loop-to-loop knot quickly and consistently, even in adverse weather or low-light situations.

To make a loop-to-loop connection, you must create a loop on both the fly line and the leader/tippet using suitable knot techniques like the Perfection Loop or Double Surgeon’s Loop. 

Then, you join the loops by passing one loop through the other and securing it with a simple pull.

Whether you’re a fly angler or use other fishing techniques, mastering the loop-to-loop knot can enhance your fishing experience, making it easier to adapt to changing conditions and improve your chances of success on the water.

Practice tying the knot before heading out to ensure confidence and proficiency in executing this essential fishing connection.

FAQs

How do you loop two loops together?

To loop two loops together, you pass one loop through the other and pull them tight to secure the connection. 

This creates a loop-to-loop knot, allowing you to quickly and easily attach or detach fishing components like a leader or tippet to a fly line in fly fishing or other fishing setups.

How strong is a loop-to-loop knot?

A well-tied loop-to-loop knot is generally considered very strong and can retain a significant portion of the line’s original strength.

It can retain about 80% to 100% of the line’s breaking strength when tied properly, depending on the specific knot used and the line type.

 The strength of a loop-to-loop knot can vary based on factors such as the knot type, the material of the lines being connected, and the quality of the knot tying.

Knots like the Perfection Loop or Double Surgeon’s Loop are known for their strength and reliability in creating loop-to-loop connections.

It’s important to note that while loop-to-loop knots are strong, they can weaken over time due to wear, friction, and exposure to UV rays.

 Inspecting and potentially retying the loop-to-loop connections regularly to ensure optimal strength and performance for critical fishing situations or when targeting large and powerful fish.

What is a loop in knots?

In knots, a loop refers to a closed, circular, or oval-shaped structure formed by bending and crossing a line back on itself to create a secure and strong attachment point.

 Loops are commonly used in various types of knots for various purposes, such as creating connections, attaching hooks, creating anchors, or forming handles.

Loops provide versatility and convenience in fishing, camping, climbing, sailing, and other activities that involve ropes and cords.

What is the strongest loop knot for rope?

The “Bowline” knot is considered one of the strongest loop knots for ropes. It forms a secure and reliable loop that does not slip or jam under normal conditions. 

The Bowline is widely used in various applications, including camping, boating, climbing, and general-purpose rope work, where a strong loop is required. 

It is easy to tie and untie, making it a versatile and popular choice for creating a loop in a rope.
