The Danielson Crane Swivel is terminal tackle item used for tying specialty fishing rigs. Danielson's crane swivel is a good choice for most fishing situations. Similar in design to the barrel, the crane swivel out performs the barrel when under pulling tension. Catfish are notorious for twisting, thus it's a good idea to use fishing swivels on trotlines. We offer the Danielson Crane Swivel in seven sizes of the black color. Quantity varies see below.
