The Line Aligners from POLE POSITION is an aid to make the hook tighten/hook better. You create, as it were, an extension of your hook shank and it is important that the Line Aligner is not too slack. This is where our Line Aligner stands out. The stiff material fits seamlessly with the hook shank and an effective hooking is guaranteed. In addition, this Line Aligner is the most subtle on the market. With the two well-camouflaged colors you can work on any soil type. The 'Shorty' version is ideal for long shank hooks and the 'Medium' version is ideal for short shank hooks.
