The Korda PTFE Spinner Ring Swivel XX is built around the principle that a spinner rig works best when the hook is free to spin and take a hold in the mouth of the carp. The more freely it spins, the better the chances of getting a hook hold, and that is exactly what this swivel is designed to achieve. This size 11 swivel is made specifically for use with the spinner rig and suits various hook link materials, as the ring removes the need for a connecting loop. As with the standard version, the hook can easily be added or removed from the crook at the other end, which is then covered with a Kicker to keep everything securely in place. The XX version is designed for use with larger hook sizes such as 1s and 2s. It has a thicker wire gauge than the original version and should be used with the XL Kickers, which sit snugly over the crook and the larger eye of the bigger size hook. Polytetrafluoroethylene (PTFE) has one of the lowest friction coefficients of any solid material, making it ideal for coating swivels as it reduces friction between the barrel and the eye. - Sold in packs of eight - A version without a ring is also available
