TRONIXPRO Running Beads are designed for use on any type of running rig, this swivel and bead combination is ideal for popular rigs such as the Wessex rig and the simpler running ledger. The oval plastic helps to distribute the weight of the lead evenly along the line, preventing damage and providing a smoother transition of the line when a fish takes, as opposed to a straight swivel. They are also perfect for Portland rig fishing, providing both the buffer bead and swivel in one piece of terminal equipment for the sliding snood. These beads are not designed to take the full power of a throw and are not suitable for pulley installations.
