The special fin, patented, greatly facilitates both the hooking and the smoothness of the metal wire, largely reducing the workforce both in the installation and in each subsequent processing. The absence of protruding parts and the totally smooth surface makes it more comfortable, practical, manageable.  Galvanizing, in addition to ensuring a duration over time of the "guardian" equal to that of the vineyard, eliminates the release of pollutants into the surrounding environment, even in the case of totally mechanical harvesting. Easy installation, small size, excellent value for money, are combined with a high quality of our "quick coupling brace".
