Trilene Knot
Double pass through eye plus clinch-style wraps. Extra eye friction vs single-pass clinch.

Connection card
Trilene Knot
For line → hook, line → lure, line → swivel.
This card does not say how strong the knot is. A retention figure comes from a bench, in one material, at one diameter, tied by somebody who ties it all day — and the line in your hand is none of those. What it does tell you is whether the thing you have just tied is the thing the record describes.
What this plate is telling you
Double pass through eye plus clinch-style wraps. Extra eye friction vs single-pass clinch.
Save this as a picture and it works with a dead signal and a nearly dead battery, which is when a joint is most often tied badly. The rest of this page — the steps, the seating sequence, the failure modes and the bench — is for the evening before.
Before you start
- ·The line passes through the eye twice, so the eye has to be large enough to take two turns of your line. Check this on small hooks.
- ·NetKnots lists it for tying monofilament or fluorocarbon to swivels, snaps, hooks and lures.
- ·On heavy line, hold the hook with pliers so you can pull hard enough to seat the knot.
- ·Trim the tag to a stub of about 3 mm (an eighth of an inch) rather than flush.
Step 1 of 4 · move 1 of 1. Push the tag through the eye, then through again, leaving a small double loop

01.1
Push the tag through the eye, then through again, leaving a small double loop
- Hold:
- Left hand holds the hook, eye toward you
- Move:
- Right hand feeds the tag through the eye a second time, the same way as the first
You should now see: Two turns of line through the eye lying side by side, a small double loop at the eye, and a long tag.
Pass the tag end through the eye, then pass it through again in the same direction, leaving a small double loop of line on the far side of the eye.
Two turns of line through the eye forming a small round double loop that a fingertip can fit through, with a long tag left over for wrapping.
Pulling the double loop closed against the eye, or letting its two strands spread apart. A closed loop leaves no opening for the tag at step 3.
Fix: Open the double loop again and keep a fingertip in it while you wrap, so both strands stay together and open.
Why: The two passes share the contact with the eye between two strands. Animated Knots notes this helps retain line strength, especially when the eye is wider than the line.

1Two passes through the eye2Tag endStep 1 of 4 · move 1 of 1
Push the tag through the eye, then through again, leaving a small double loop
Hold: Left hand holds the hook, eye toward you. Move: Right hand feeds the tag through the eye a second time, the same way as the first.
You should now see: Two turns of line through the eye lying side by side, a small double loop at the eye, and a long tag.
Step 02 / 4
Wrap the tag end around the standing line 5 or 6 times, working up the line away from the eye.
You should now see: An even spiral of 5 or 6 turns on the standing line above the eye, with the double loop still open below it.
If it goes wrong: Turns that cross or pile on top of each other, seen as a bump in the spiral. It often happens when the double loop is let go and the line twists.
Fix: Unwind to the eye, check the double loop is still open, and wrap again with light tension so each turn sits beside the last.
Why: The turns close onto the standing line as a coil when the knot is pulled. A crossed turn presses on one spot of the line instead of sharing the grip along the coil.
1Five turns about the standing line2Double loop beside the eyeStep 2 of 4 · move 1 of 1
Wrap the tag round the standing line five times, working away from the eye
Hold: Left finger and thumb pinch the double loop open at the eye. Move: Right hand turns the tag round the standing line, one even turn at a time.
You should now see: An even spiral of five turns, with the small double loop still open between the eye and the first turn.
Step 03 / 4
Bring the tag end back down to the eye and thread it through both strands of the double loop together.
You should now see: The tag passing through the double loop beside the eye, with both strands of that loop lying around it.
If it goes wrong: Threading the tag through only one strand of the double loop. Look closely before pulling: the tag should have two strands around it, not one.
Fix: Pull the tag back out and thread it again through both strands at once, before putting any pull on the knot.
Why: Passing through both strands ties the double loop and the turns together. Through one strand only, the other strand is left free and the turns can unwind under load.
1Double loopStep 3 of 4 · move 1 of 1
Bring the tag back and pass it through the double loop beside the eye
Hold: Left hand keeps the turns from unwinding. Move: Right hand threads the tag through the double loop, between the eye and the first turn.
You should now see: The tag through the double loop at the eye, with both strands of that loop around it and the turns still even.
Step 04 / 4
Wet the knot and pull the standing line against the hook with slow, steady pressure until the turns close on the eye. Trim the tag, leaving a stub of about 3 mm (an eighth of an inch).
You should now see: A tight coil of turns right against the eye, the double loop snug around the eye, and a short stub of tag left standing.
If it goes wrong: Stopping before the knot reaches the eye, or pulling hard on dry line. A gap shows between the coil and the eye, or the line looks crinkled after the pull.
Fix: If there is a gap, wet the knot and pull again slowly. If the line is crinkled or the knot will not close, cut it off and tie it again.
Why: Animated Knots advises against trimming the Trilene tag too short. A small stub leaves the tag room to draw in slightly as the knot settles under load without pulling out.
Step 4 of 4 · move 1 of 1
Wet the knot, draw the turns down against the eye, and trim the tag
Hold: Left hand holds the hook. Move: Right hand pulls the standing line slowly until the turns close against the eye.
You should now see: The turns closed into a neat barrel against the eye, the double loop snug on the eye, and a short tag.

Seating sequence — where failures are born
The step list compresses the finish. Run these phases in order, one at a time.
01 Moisten
Wet the structure before any load reaches it.
Zero. Nothing tightens yet.
02 Load
Take up slack slowly until the wraps begin to gather.
Light and even — both ends moving together.
03 Dress
Watch the wraps stack in order; stop and back off if any cross.
Hold, do not pull. Correction happens here or not at all.
04 Set
One continuous pull to full seat — no sawing, no jerks.
Firm, single direction, standing line against the terminal end.
05 Trim
Cut the tag square, leaving a short stub proud of the knot.
None. Never trim under load.
Finished structure — what correct looks like
Drawn from a rope model of this knot: which strand passes over which comes from where the rope actually lies.
- ·Double-pass eye with neat wrap stack
- ·Snug to eye
- ·Tag through both loops then seated
- ·Parallel wraps
Verify before you load it
Every line is pass or fail. One fail means retie — do not load a knot you argued with.

Field notes — dark, cold, gloves
- ·Retie by feel first, light second — the seat is a tactile event, not a visual one.
- ·Gloves off for the dress phase. Fabric hides a crossing wrap.
- ·Wrong twice in a row means the material or the hardware is fighting you. Change one, not your technique.
Load direction
The pull is carried by two loops around the eye instead of one, so the metal edge takes half the pressure at any point. The coil behind them does the gripping, exactly as a clinch does.
Two turns on the eye, not one. That is the whole difference from a clinch, and it is worth about the same again on a thin hard line.
Trilene Knot — finished-state checks, on the shared reference layout
When this family fails, it fails as these. The recovered end still outranks the name.
Wraps down the standing part, then a tuck that jams the barrel to the eye.
- !Wraps walked or crossed — load on one turn of the barrel
- !Barrel never jammed to the eye, so the tuck is decoration
- !Tag never tucked, or the extra Improved / Trilene pass missing
- !Tag threaded through only one strand, so the turns can unwind under load
- !Double loop slipping behind the eye as the knot is pulled tight
- !Pulled tight dry or fast, leaving the line crinkled
- !Tag trimmed flush, with no stub to draw in as the knot settles

Get it right with everything in your favour0/5 clean
Good light, dry hands, a table. Until the sequence is automatic here there is nothing for the harder rungs to test — you would only be learning that difficult conditions are difficult, which you already knew.
How · Tie it, check it against the list, log it. Five clean and the ladder opens.
Nothing marked. Log it clean, or mark what happened first.

Strength, and where the number comes from
Not established
No break test naming this knot with a measured control was found; the 'high 80s–90s' band it used to carry has no publisher behind it that we could locate.
Percentages come from published tests on their own line, their own knot-tyer and their own pull rate. Yours is a different system. Treat a figure as a reason to test, not as a result you already have.
