How to Tie the Bull Hitch (Method 3: Carabiner Clip-In)
Usage
The Bull Hitch (Method 3) is the way to tie the Bull Hitch when you need to clip the finished loop straight into a carabiner or other hardware. You build a girth hitch, cross the two loops into the Bull Hitch's signature X, and clip in before tightening. The finished knot is the same Bull Hitch you get from the end or bight methods — this route just leaves a ready loop for the hardware.
Its best-known job is seating a carabiner in a Prusik loop. Clipping in with the Bull Hitch keeps the loop from sliding around the carabiner, which helps avoid side-loading the gate — a real weak point, since Petzl's own carabiner-loading guidance puts a gate-loaded carabiner at only about 30% of its rated strength. Avoiding that side-load is the one place this hitch earns a genuine, function-specific edge over a plain girth hitch clip-in.
Why Learn the Bull Hitch (Method 3)?
If you already clip cord loops into carabiners — on a pack, a Prusik knot loop, or a keychain — this method puts the extra security of the Bull Hitch exactly where the hardware sits. Bear Essentials' clip-in rule: the X is the knot — cross the ears before you clip, because a Bull Hitch left parallel is just a girth hitch wearing the wrong name. It is the fiddliest of the three tying routes, so practice it at home before you rely on it. A few runs with the Knot Tying Kit practice cord will settle the ear-and-wrap sequence — practice cord only, not rated hardware or line.
Common Uses
Climbing and Rigging
- Clipping a carabiner into a Prusik loop so the loop can't slide around and side-load the gate.
Utility and Everyday
- Attaching paracord lanyards to key rings.
- Securing flashlight lanyards.
- General-purpose secure cord attachments — a job where a quality cord like the 750lb Bushcraft Paracord holds the X-crossing cleanly.
Camping
- Permanent or semi-permanent cord attachments where a simple hitch may work loose.

Notable Features
- Anti-Side-Load Clip-In: The X-crossed loop keeps a clipped carabiner seated instead of letting the loop slide around it.
- Improved Security: Holds more reliably than a plain cow hitch and resists slipping and working loose over time.
- Compact and Inspectable: Small footprint, and the visible X gives you a clear check that it's dressed right.
Similar Knots
Bull Hitch (End Method) vs. Bull Hitch (Method 3: Carabiner Clip-In)
- Advantage: The Bull Hitch is faster and less fiddly when you have a free rope end to work with.
- Disadvantage: Doesn't leave a ready loop for clipping hardware in as you tighten.
Bull Hitch (Method 2) vs. Bull Hitch (Method 3: Carabiner Clip-In)
- Advantage: The Bull Hitch (Method 2) is tied entirely in the bight — no rope end and no hardware access needed.
- Disadvantage: Not built around clipping in, so it skips this method's carabiner-seating benefit.
Cow Hitch (Lark's Head) vs. Bull Hitch (Method 3: Carabiner Clip-In)
- Advantage: The Cow Hitch (Lark's Head) is simpler and quicker to tie and untie.
- Disadvantage: More prone to slipping and working loose under uneven tension.
Girth Hitch vs. Bull Hitch (Method 3: Carabiner Clip-In)
- Advantage: The Girth Hitch is the fastest clip-in of all — it's the base this method starts from.
- Disadvantage: Without the X-crossing, the clipped loop can slide and side-load the carabiner.
Security Level
Bear Essentials judges the Bull Hitch more slip-resistant than a plain cow hitch — informal tug tests and community discussion point the same direction, though no instrumented breaking-strength study exists. One myth worth busting: that does not make it proven stronger — no instrumented breaking-strength test of the Bull Hitch exists, and slip resistance and breaking strength are different questions. All of its security lives in the dressing: seat a true X against the carabiner, because parallel strands give you none of the anti-slide benefit.
Downsides
- Fiddliest Route: Enlarging one ear, wrapping it around the other, and clipping in makes this the slowest and most finicky of the three Bull Hitch methods.
- Not Quick-Release: Harder to remove than a basic cow hitch, and it requires access to the attachment point to untie.
- Can Bind After Load: After heavy loading it may need to be worked off the hardware — don't assume an easy release.
Structure
Method 3 starts from a girth hitch — a pair of opposing half hitches — then enlarges one "ear," wraps it around and through the other, and clips a carabiner through the resulting loop before tightening. The extra crossing gives the finished form its signature X, where the strands pinch against each other and the hosted object. Dressed with parallel strands instead of a crossed X, the same structure is known as the Piwich Knot.
History
The Bull Hitch's parent, the cow hitch, is an old, well-catalogued knot, but the Bull Hitch itself appears only in modern knotting sources — there is no entry for it anywhere in Ashley's Book of Knots.
How to Tie the Bull Hitch (Method 3: Carabiner Clip-In)
This carabiner clip-in sequence is the standard Method 3 build. The wrap-and-cross moves are the part people mix up — which ear wraps where is easy to lose track of mid-tie. The Knot IQ app keeps the Bull Hitch and its sibling methods side by side so you can check your finished hitch against the correct form.
Step 1
Make a girth hitch around your cord's anchor point.
Step 2
Make one "ear" of the hitch large by pulling slack from the other side.
Step 3
Wrap the left ear around the back.
Step 4
Pass it around the right ear.
Step 5
Pull your finger through the loop.
Step 6
Clip the loop into a carabiner and tighten the knot, seating the X snugly before final tension.
FAQ
Is Method 3 a different knot from the End or Bight methods?
No — it produces the same finished Bull Hitch. This route just dresses the knot so the working loop clips into a carabiner. It is the fiddliest of the three ways to tie it.
What is Method 3's most safety-relevant use?
Clipping a carabiner into a Prusik loop so the loop can't slide around and side-load the carabiner gate.
Is the Bull Hitch proven stronger than the Cow Hitch?
No. It is community-supported as more slip-resistant, but there is no breaking-strength test showing it is stronger — strength and security are different questions.
Does the Bull Hitch (Method 3) untie easily?
Not always. It's not quick-release, it's harder to remove than a basic cow hitch, and after heavy loading it may bind and need to be worked off the hardware.
Important Notes on Safety
The Bull Hitch is not intended for life-support or critical load-bearing applications. It has no published strength data and no climbing-authority endorsement, so anything load-critical belongs on rated, inspected gear and systems — and any clip-in should be checked to confirm the carabiner is not side-loaded after tightening.
