This is a cut length 2.2m - check if this is enough for your needs. For both sides of the kayak rudder cable you will need 2 (QTY=2).
This flexible nylon tubing is 3/16" diameter (a little more). The Stainless Steel Wire 1/16" fits easily through this tube. The 2mm Spectra cord does as well (spectra is a firmer fit than in our per metre tubing - will go through but don't have a thick end on the spectra from the hot knife cutting).
This type of nylon tube is useful for:
Internal Diameter: 2.5mm approx.
External Diameter: 5.1mm
Colour: Black
