The frame contains 20 beads, 10 with a large bore and 10 with a small bore with a central membrane. The large bore bead is a perfect interference fit over the 0.5mm silicone tube supplied with the beads. This is designed to be fished as the upper bead on the leadcore leader, so that in the event of a break off the bead can easily pop off the silicone tube under minimal pressure, and slide over the leader knot, allowing a hooked fish to rid itself of the leader.
