The Tubes are designed to fish your Tubefly with an absolute free swinging hook.

Your Fly runs absolut straight and tangle free, plays much better and you will loose less fish.
If you would like to fish with a smaller Swing-Tube you can cut the Swing-Tube on each length you like.

Please use only hooks which fit ideal into the Swing-Tube.
All hooksizes and brands you can use you will find on this side behind the artikel.

If your hook (eye) is to big the Swing-Tube will break.
