Designed for any rig that incorporates a sliding ring on the hook shank, ESP Shank Stops are housed on a handy frame that can be stored neatly in the tackle box. No more problems trying to extract a tiny stop from a flip top box! -The frame contains 40 stops, 20 of each mini and small. The mini stops are perfect for hook sizes 8 and 10 whilst the small are best suited to larger hooks. -Moulded in a soft, clingy material in a conical shape, the holes at each end do not quite meet in the middle, leaving a central membrane which is pierced by the hook point resulting in a secure, tight fit on the hook shank which will not slip on the cast and therefore requires no gluing.
