SECO’s construction-grade fiberglass surveyor rod is perfect for surveying, plot mapping, grading and leveling. Measurements are printed on the side of this fiberglass grade rod in tenths of feet. It has a rectangular shape with rounded back corners to improve grip. This shape also lets you mount laser detectors without additional hardware. The scale covers the entire face of the fiberglass grade rod, and a measuring scale on the back allows for overall height readings. Standoff ribs reduce wear. These fiberglass leveling rods are lightweight, non-conductive and non-corrosive, ensuring years of use. Collapsed length for these poles is 58 3/8 inches. When fully extended, the poles have a total length of 20 feet.
