The arbor knot is a simple fisherman’s knot used to attach a fishing line to the arbor of a reel.

The arbor knot may look complicated, but if you practice it a few times, you’ll get it.

Tying the Arbor Knot

  1. Wrap the line around the spool using the tag end in a clockwise direction.
  2. Make a loop around the standing line with the tag end. Tie an overhand knot and pull until it’s snug.
  3. Make a second overhand knot in the tag end right above the first one. (Optional, you tie the overhand knot in the tag first if you’d like).
  4. Slide both knots to tighten against the spool. Use saliva or liquid to reduce friction.
  5. Clip the tag end.

  • Backfill the knot with mono when putting the braid on a reel or using tape to prevent slipping.
  • If you have a highly polished and slippery reel, increase friction by winding the line multiple times around the arbor and then making the first knot. The wraps should be tight around the spool as you turn.
  • Moisten the line before pulling. This will reduce friction when you are tying the line to the reel and when you are tying the arbor knot.


  • It will not slip off when you are winding the fishing line around the spool.
