Gripper beads are lightweight, discreet, small and pliable. They are made from soft TPE material with a tapered bore and the colours/sizes are matched to Hi-Viz Shockcore hollow elastic - just thread on easily with a pole-threader. Once in place they retain the elastic, but can then also be slid-up the elastic to make small adjustments to its tension. In conjunction with Middys Pull-It Side PTFE Bush, they create a precise set-up. Recommended by elite match anglers such as Kieron Rich.
