Set consisting of four elements:
• Two soft rubber stoppers
• A rolling swivel, with clip for quick connection to a hooklink or to paternoster arm
• A rubber tapered sleeve, which also acts as an anti-tangle device, because it takes the arm to 90° to the main line.
The whole set is mounted on a convenient binder that contains 6 sets and allows to transfer the entire thing on to the main line in a very quick time, without the risk of losing any single component.
