Unlike our other links, this is based around a crane swivel which is machined to be one of the strongest and smoothest swivels around. Strong wire forms the clip which is bent at the end, so it locks into the lock mechanism securely. They are ideal for attaching rigs, weights when boat fishing and lures in their smallest sizes.
