Fixed-size non-slip loop for free-swinging lures and flies.

Applications How to tie it

Finished structure

Drawn from a rope model of this knot: which strand passes over which comes from where the rope actually lies.

1Loose overhand
2Tag through the eye
Move 1 of 1Tie a loose overhand in the line, then push the tag through the eyeYou should now see: An open overhand in the line, the lure on the tag below it, and a long tag past the eye.
Step 01
Tie a loose overhand knot in the line about 25 cm (10 in) from the end, then pass the tag end through the eye of the lure or hook.
You should now see
An open overhand knot in the line, the lure hanging on the tag below it, and a long tag past the eye.
If it goes wrong
Pulling the overhand snug while handling the lure. A closed overhand will not let the tag back through at the next step.
Fix: Work the overhand open with a fingertip until the tag can pass through it easily.
Why: The overhand is where the tag enters twice, once at step 2 and again after the turns. It stays loose until the final pull draws it down against the turns.
1Back through the overhand
2Loop to the lure
Move 1 of 1Bring the tag back through the overhand, the same way it came outYou should now see: The lure hanging in a loop below the overhand, with the tag coming out of the overhand beside the standing line.
Step 02
Bring the tag end back through the loop of the overhand knot, so the lure hangs in a loop of line below it.
You should now see
The lure hanging in a loop below the overhand, with the tag coming out of the overhand beside the standing line.
If it goes wrong
Running the tag past the overhand instead of through it. Nothing then holds the lure loop, and it slides shut on the eye.
Fix: Follow the tag from the eye with a finger. If it does not pass through the overhand, pull it back and thread it through.
Why: The overhand works as a collar. The tag passes through it here and again after the turns, so when the overhand closes it holds the tag at both ends of the turns.
1Five turns round the standing line
Move 1 of 1Wrap the tag round the standing line five times, working away from the overhandYou should now see: An even row of five turns on the standing line beside the overhand, with the tag end free at the far end.
Step 03
Wrap the tag end around the standing line, working away from the overhand. Use about 5 turns on mid-weight line, up to 7 on light line and as few as 2 on very heavy line.
You should now see
An even row of turns on the standing line above the overhand, with the tag end free at the far end of the row.
If it goes wrong
Turns crossing over each other or bunching, seen as a lump in the row. On fine line it is also easy to lose count and wrap too few.
Fix: Unwind back to the overhand and wrap again, counting out loud and laying each turn beside the last.
Why: Stiff heavy line cannot close down around many turns, while thin light line needs more turns to build enough grip. That is why the count drops as line weight goes up.
1Back through the overhand
Move 1 of 2Pass the tag back through the overhand from the side it came out of
Move 2 of 2Set the loop size, wet the knot, pull the tag, then pull loop and line apartYou should now see: A compact knot above an open loop of the size you set, the lure swinging freely, and a short tag.
Step 04
Pass the tag back through the overhand from the side it came out of before. Set the loop size, wet the knot, pull the tag to snug the turns, then pull the loop and standing line apart and trim.
You should now see
A compact knot above an open loop of the size you set, the lure swinging freely in the loop, and a short tag.
If it goes wrong
Bringing the tag back through the overhand from the wrong side, or pulling the standing line hard before the turns are snug. The loop shrinks toward the eye as you tighten.
Fix: If the loop has closed or come out too small, cut the knot off and tie it again, setting the loop size while the turns are still loose.
Why: The loop size can only be changed while the turns are loose. NetKnots draws the turns together with a slow pull on the tag first, then seats the knot by pulling the loop and standing line apart.

Failure modes

When this family fails, it fails as these. The recovered end still outranks the name.

Non-Slip Mono Loop — what fails and what to do — Hook the Horizon reference plate

Fixed-loop family

A loop that stays the size you made, with a return that cannot cinch.

!Loop cinched around the hardware — action is dead
!Return path reversed, so it becomes a slip loop
!Fluoro in a lock that only behaves on mono

Fails when

!Tag brought back through the overhand from the wrong side
!Tag not passed through the overhand, so the loop slides shut on the eye
!Standing line pulled before the turns are snug, closing the loop toward the eye
!Too few turns on light line to build enough grip

Geometry

Too few wraps on light line
The loop walks down and becomes a noose
Wrap friction above the overhand is what holds loop size · step 03
Loop cinched closed while seating
Free-swing is gone and the noose can cut
Seat the wraps without shrinking the overhand loop · step 04
Tag missed the overhand
This is a slip loop, not a non-slip
The tag path through the overhand is the lock · step 02
