Non-Slip Loop Knot (Kreh Loop)

Dockrig is reader-supported. When you buy through links on this page, we may earn a commission.

The non-slip loop ties a fixed loop at the lure eye. The lure swings free inside the loop instead of being clamped by a knot.

Turns depend on line test: 7 for 6 lb and lighter, 5 for 8 to 12 lb, 4 for 15 to 40 lb. That's Lefty Kreh's table. Braid gets 6.

These are Kreh's numbers for mono. He gives 6 turns for braid and 1 for coated wire. The idea is simple. Thin line needs more wraps for grip. Thick line needs fewer, or the knot won't close.

Too few turns and the knot may slip. Too many and it won't draw down neatly. Stick to the table.

Kreh's table doesn't give a fluoro row. For fluoro, we follow the mono row for the same lb test.

The 5 steps

  1. Tie a loose overhand knot about 8 to 10 in. from the end. Don't tighten it.

  2. Pass the tag through the lure eye, then back through the overhand. It must go back in on the same side it came out.

Loop size is set in step 1. Slide the overhand closer to the end of the line before step 2 for a smaller loop. On 8 lb line, a loop of 1/8 to 1/4 in. is plenty.

Step 2 is where most knots go wrong. If the tag goes back through the wrong side of the overhand, the knot won't lock. Check it before you wrap.

In step 5, pull all 3 parts. Kreh made a point of it. If you only pull the standing line, the wraps can close unevenly.

Why a loop knot at all?

A clinch or Palomar grips the eye tight. The lure moves with the line. A loop lets the lure rock and swing on its own.

That matters most with lures that rely on loose action.

Some anglers tie loops on everything. Others use them only for jerkbaits. We'd say try it where lure action is the point.

Hooks and flies under about #12 are a poor fit, per Kreh. The loop is too big next to a tiny eye.

Many jerkbaits and small cranks come with a split ring on the nose. You can tie the loop to the ring, or take the ring off and tie to the eye.

Split ring pliers open the ring without a bent fingernail. They also give you a grip on the lure for the final pull.

Line type differences

LineTurnsNotes
Monoby tablethe knot Kreh's numbers were written for
Fluorofollow the mono row by lb teststiffer; wet well and seat firmly
Braid6thin and slick; leave a longer tag, about 1/8 in.

Fluoro is stiffer than mono at the same test, so the overhand and wraps take more care to close neatly without kinks. Wet it, pull slowly, then give it a hard final pull.

Braid is the opposite. It's thin and soft, so it closes easily. The risk is slip. Kreh's 6 turns cover that. Trim the tag a bit longer than on mono.

On a braid main line with a fluoro leader, tie the loop in the leader. That's the usual case on bass water. Use the fluoro row.

The 2 knots start the same way. The Rapala knot adds a final pass through the loop it makes. Both leave a fixed loop at the eye.

Rapala promotes the knot for its own lures. Either works for a free-swinging lure. We'd pick 1 and learn it well.

Where it fits on the water

Common mistakes

  1. Wrong side in step 2. The tag must re-enter the overhand on the same side it came out. Otherwise the knot pulls apart.
  2. Too few turns on light line. 4 turns on 6 lb is under Kreh's 7. Count them.
  3. Overhand pulled tight too early. Then the loop is huge or the tag won't pass. Keep it loose until step 5.
  4. Pulling only the standing line. Pull lure, standing line and tag together first.
  5. Loop too big on a small lure. Slide the overhand down before you pass the eye.

Checking the knot

If the loop shrinks under the pull test, the knot slipped. Retie with the full turn count.

When to skip the non-slip loop

Common Questions

Is the non-slip loop the same as the Kreh loop?

Yes. Lefty Kreh made the knot popular and published the turns table. Many anglers call it the Kreh loop. Some call it the non-slip mono loop.

Does a loop knot work with a snap?

You don't need both. A snap already lets the lure swing. A loop knot does the same job without the hardware.

On a split ring, a loop still helps a bit. Many anglers tie a loop straight to the split ring.

How small should the loop be?

Small enough to look neat, big enough to swing. On light line, 1/8 to 1/4 in. is common. On 20 to 40 lb leader, a bit bigger is normal.
