Flexible fence with steel wire rope, steel grille, steel column and pressure reduction ring. Set at a certain position on the slope, used to intercept the falling stone (or falling object) on the slope to avoid damage to the protected object, so it is also called the stone stop net. When set in the debris flow area, it is convenient to form a flexible fence to intercept the large solid particles in the debris flow. According to the different energy levels, it is divided into three models: RX-025, RX-050 and RX-075. Indicate that the impact resistance energy is 250, 500 and 750 kJ.
