-The feeder tube is made of softened plastic, which is good for its excellent flexibility and and the same time it is stiff enough. Thanks to this material it is possible to use tubes in a very cold water without any risk of damage. The feeder is fixed on the tube by a snap hook that moves on the spring steel eyelet. As a result, it rotates very well around the tube axis and prevents assembly tangling. There are soft plastic stops at both ends of the tube. This holder is characterized by a high degree of elasticity, resulting in a high load capacity. There are 5 tubes in the package.
