A well-made rubber bead, or rather a connector that allows you to change the leader in no time. At the same time, its shape and size have been selected to fit perfectly with all Matrix Evolution pass-through feeders. Top quality! The main line is led through the cap and tied permanently to the connector, the leader is ended with a loop, simply hooked by the eye of the connector and locked with a pass-through cap. This solution allows you to quickly change leaders without untangling them and cutting the loops, and thus their further use. It is much faster when conditions change quickly and we want to adapt to them. It completely eliminates the need for a swivel and guarantees optimal protection of the knot against lead or feeder passage. In addition, it guarantees the maintenance of the linear strength of the cable, without losing the strength at the knot.
