Ranging poles are used for marking and signalling terrain or boundary points during construction and surveying work. In addition, ranging poles are used for escape and evacuation, where a third ranging pole is inserted in the straight line between two poles. The two-colour paint makes the alignment rods easily recognisable even from a distance. The colour fields are 50 cm long. In order to make it easier to escape, ranging poles are often placed in rows with alternating heads. Sturdy steel tips are used for robust work on hard ground. Only the best steel (Ø 27 mm) is used for this alignment rod. NESTLE steel alignment rods are PVC-coated for a long service life. Quality Made in Germany.
