This is the perfect choice of buffer at the swivel end for any running rig, and not only does it protect the knot but it also helps to reduce tangles significantly. It features two different external diameter sections of rubber, which join at an angle to ensure that the lead sits at the perfect angle to help avoid tangles. The Run Rig Rubber sits neatly over the hook link swivel and is compatible with any of our fused or leadcore leaders, as well as rig tubing. They come in a choice of Weed, Gravel, Clay or Silt colours to match the bottom, and you get 10 in a pack.
