The Nedo 13 Foot Fiberglass Grade Rod makes construction and survey leveling jobs easier with its built to last fiberglass construction and dual graduations scale. With an ergonomic design, this sturdy rod features an easy-to-read scale in feet and tenths on both sides. It has secure anti-jam buttons for locking the 4 sections in place, and a height of 13 feet, providing enhanced accuracy in measurements. It also has an opening on the back scale to view overall height reading. This leveling rod is non-conductive in dry conditions, as it does not produce heat or electricity. A snap on rod level and carrying bag is included for convenience. A 2-year warranty is included.
