Black whipping thread grade D 4oz bulk professional spool. Ideal for building carp rods. This is the thread we use to build Harrison Rods. One spool will build many rods, just how many we have never checked but will keep a professional going for weeks.
A tip for beginners. Make tying easier by preparing the guide feet with a file to get a smooth gradual ramp. Most guides are factory linished, but there is always room for a little more smoothing to make the job easier. This will make it easier to get a gap free trasnition up the foot with no metal showing through.
