Mustad Rubber Beads are an essential component when making any moving rig, such as the running ledger or the pulley rig. By using Mustads rubber beads above a mainline or rig body knot, abrasion caused by other moving components such as weights and booms can minimized if not completely stopped. Mustad rubber beads are particularly effective when using a running ledger rig while uptiding from a boat or bait fishing from the shore while targeting bass.
