System with guide rails for the protection of an orchard from weather conditions, which consists of a row of columns (1,2) with each column (1,2) stabilized in its base by one side, and on the top of each column (1,2) a pin (5) is placed onto which a pivoting arm (6,7) is rotationally positioned, while a middle cable (9) is run through a cross-sectional opening on the pin (5), and the ends of pivoting arms (6,7) are each connected via a single end cable (8), through a guide rail (11);
- over the pivoting arms (6,7) a rectangular cover (10) is placed, which has a sliding connection to the middle cable (9) by its middle section, and a sliding connection to end cables (8) through its longer sides, wherein a rotational guide rail (11) consists of a stud screw (13) connected to the end cable (8) on one end by tightening the cable (8) between two nuts (16.1, 16.2) screwed onto the same end of the screw (13), while the connection of one end of the screw (13) and side cable (8) is placed inside the cylindrical casing (12) or a cap (12.a), and the other end of the screw (13), with a fashioned head of the screw (13), is rotationally connected to the end of each pivoting arm (6,7), so that the rotational axis of the screw (13) is parallel to the rotational axis of the pivoting arm (6,7).
