This type of scarecrow will effectively protect your pipes, tubes and pipes against pollution from birds. The strings holders must be mounted at a distance of 1.5 m from each other, and the correct tension of the strings is ensured by the use of springs. Each holder is fixed arround the tube by the screw at it ends. You can find scarecrows suitable for different tube diameters and with different numbers of supporting spikes either with or without protection against underflying.
