Rubber sleeves for trebles and big singles The Zeck Treble Sleeve is a soft rubber sleeve that locks whipping and wraps on the hook shank, keeping rigs neat and secure. With an inner diameter of 3 mm and a length of 20 mm, it fits most trebles and larger single hooks without affecting hook penetration. Each pack contains 10 pieces, enough for several deadbait traces and predator rigs.
