The Danielson Barrel Swivel is a small terminal tackle item consisting of two rings connected to a pivoting joint. The Danielson Barrel Swivel attaches to the main line on one end and a leader on the other end often finished by a hook, lure, or sinker. The main use of the Danielson barrel swivel is to allow the line to untwist during line retrieval, preventing undesirable tangling. A secondary benefit of the fishing swivel is that it may stop a sliding sinker, which depending on the fishing method may be placed before or after the swivel. We offer the Danielson Barrel Swivel in nine sizes of black color.
