In bad weather, the line is broken, so you can also get the same exercise in the dismantling and reassembly. The structure is self-explanatory and works as tension belts with ratchet. By printing on only one side of the line you can see immediately whether the line has twisted and correct if necessary again even before tensioning. The Line is ready for use in less than two minutes, broken down even faster. Beautiful is that the package was kept spacious, so that the wound line without any problems can be stowed in it again and again.
The tree saver I had been once in use. They make me a robust impression.
