How to Tie a Rock Climbing Knot: Your Expert Guide to Tie-Ins, Anchoring, and Essential Safety

Hey climbers! Ready to lock in your safety system and climb with absolute confidence? Knot mastery isn’t just a useful skill; it’s the non-negotiable bedrock of system integrity in rock climbing. The difference between a solid day out and a scary moment often comes down to how well you tie, dress, and inspect your knots.

In climbing, we talk about three main types of “knots”:

• Knots (True Knots): Hold their form without needing to be tied around anything.
• Hitches: Must be tied around an object (like a carabiner or anchor) to hold together; they fall apart if the object is removed.
• Bends: Used specifically to join the ends of two separate ropes or cords.

Let’s dive into the essential knots you need for a secure day on the rock.

I. The Non-Negotiable: Figure Eight Follow-Through (F8FT)

If there is one knot every climber must master, it is the Figure Eight Follow-Through (F8FT). This is the universally established standard for connecting the climbing rope directly to your harness.

The F8FT is favored because it is strong, self-cinching, and reasonably easy to untie even after being heavily loaded. Crucially, its clean lines and visual symmetry make it incredibly straightforward for your climbing partner to inspect and verify—a vital safety attribute.

Tying the Figure Eight Follow-Through: Step-by-Step

This knot uses a rethreading technique to link the rope to a closed ring or your harness.

1. Foundation: Start by tying a loose Figure 8 knot.
2. Harness Integration: Pass the tail end of the rope through the two designated hard points on your harness (parallel to the belay loop, not through it). Pull the tail so the loose knot structure sits close to the harness.
3. Retracing: Use the tail end to meticulously follow the exact path of the original Figure 8 around the entire knot in reverse. The tail must run parallel and adjacent to the standing end throughout this retrace.
4. Completion: Exit beside the standing end to complete a two-stranded Figure 8 knot.

Technical Standards for Knot Security

Achieving maximum knot strength depends on precise execution.

• Dressing: The knot must be tied perfectly, meaning every strand should lie neatly parallel or “snugly nested” against its partner, with no crossed or twisted strands visible.
• Tightening: The knot must be pre-loaded and pulled tight. You must systematically pull tight on all four strands emerging from the finished knot: the lead rope, the tail end, and the two strands leading directly into the harness.
• Tail Management: Leave a minimum of four to six inches of tail beyond the finished knot. This provides a safety margin against potential slippage or “creep”.

Expert Note on Backup Knots: While some novices may use a stopper knot for added security against a poorly tied F8FT, experts often prefer a perfectly tied and tightened F8FT without a backup, arguing that adding extra loops increases bulk and the risk of mis-clipping.

Mandatory partner inspection is essential every single time you tie in. Use this checklist:

II. Essential Anchoring and Emergency Hitches

Hitches are critical for connecting yourself to an anchor point or for emergency belay situations.

A. The Clove Hitch

The Clove Hitch is super useful for attaching the middle of the rope to an anchor. Its main advantage is adjustability: you can easily adjust your distance from the anchor without fully untying the knot. It’s also easy to untie, even after taking a heavy load.

How to Tie the Clove Hitch (Two-Handed Method)

1. Make two identical loops in the rope.
2. Put the rear loop over the top of the front loop.
3. Clip a screwgate carabiner through these two loops.
4. Pull it tight and fasten the screwgate.

Safety Warning: Always use a screwgate carabiner with a Clove Hitch. A snapgate carabiner could allow one of the loops to be pulled through, causing the knot to fail.

The One-Handed Clove Hitch (Advanced Technique)

Mastering the one-handed Clove Hitch is crucial for efficiency, especially when you are holding onto the anchor with one hand at a precarious stance.

1. Clip a screwgate to the anchor and hold it steady.
2. Clip the rope through the carabiner.
3. Grab the rope in your fist with your thumb pointing downwards.
4. Bring your hand up, twisting the rope so your thumb points upwards and toward you.
5. Push this newly formed twist through the gate of the carabiner and pull tight.

B. The Munter Hitch

The Munter Hitch is a friction hitch that can serve as an emergency belay or rappel device if your primary device is lost. It must be used with a large, pear-shaped HMS locking carabiner.

How to Tie the Munter Hitch

1. Hold the rope in both hands and form a loop by crossing the rope over itself.
2. Form a second, identical loop in the same way.
3. Fold the two loops toward each other like you are closing a book.
4. Clip a locking carabiner through both loops.
5. Test the knot by pulling tight on either end; the knot should flip easily through the carabiner.

III. Joining Ropes and Specialized Friction Knots

When ascending fixed ropes, creating permanent cord loops, or joining two ropes for an extended rappel, specialized bends and hitches are required.

A. Double Fisherman’s Bend (DFB)

Also known as the Grapevine Bend, the DFB is one of the most trusted ways to securely join two ropes. It is ideal for creating permanent loops, such as Prusik loops, due to its incredible strength and resistance to slipping.

• Downside: The knot binds tightly under tension and can become nearly impossible to untie after being loaded heavily.

How to Tie the Double Fisherman’s Bend

1. Place the ends of two ropes pointing in opposite directions so they overlap.
2. With the end of one rope, wrap it twice around the body of the other rope (like forming an X).
3. Pass the working end back through the two coils you just wrapped and pull to tighten the first knot.
4. Repeat steps 2 and 3 identically on the other rope, wrapping in the opposite direction.
5. Pull both ropes to cinch the two knots tightly together.

B. Flemish Bend (Rewoven Figure Eight Bend)

For joining two main climbing ropes for rappelling, the Flemish Bend is often preferred over the DFB because it is significantly easier to untie after loading.

1. Tie a loose Figure 8 knot near the end of the first rope.
2. With the end of the second rope, start meticulously retracing the entire path of the loose Figure 8 knot, following it exactly side-by-side.
3. Ensure the finished knot has the rope ends coming out of opposite sides of the knot.
4. Check for about a 1-foot tail and dress and stress the knot (pull slack out of all four strands).

C. Prusik Hitch

The Prusik Hitch is the most common friction hitch, used to connect a loop of thinner cord to a thicker rope. It is a staple for self-rescue, ascending fixed ropes, and crevasse rescue systems.

How to Tie the Prusik Hitch

1. Place your cord loop behind the main rope.
2. Feed the side with the connecting knot through the other side.
3. Wrap the cord around the rope loosely and feed it through again at least three times. (Use more loops if extra grip is needed).
4. Pull the hitch tight and dress it by making sure all the loops are parallel.

Conclusion: Practice Makes Perfect

Knot tying is fundamental to rock climbing safety. While knowing how to tie a knot is a great first step, achieving fluency—the ability to execute these foundational skills flawlessly, quickly, and even with one hand—is what defines mastery and enhances safety in exposed environments.

Remember the principles: meticulous dressing, thorough tightening, and diligent peer review. By prioritizing a clean, perfectly executed primary tie-in like the Figure Eight Follow-Through, and practicing essential hitches and bends until they become muscle memory, you significantly strengthen the integrity of your entire climbing system.
