Round Rod

The Round-Rod "RR" multi-helix anchors are used in areas where weak soil conditions exist and moderate holding capacities are required. All helix lead sections are 7 ft. long. Extension shafts may be required for installation to proper depth. "RR screw anchors consist of three galvanized components: Lead section, extension shaft (which includes an integral coupling), and the guy adapter. Each extension and guy adapter includes a high-strength bolt and nut." Type RR (Round-Rod) anchors torque rating is 2,300 ft-lb. Ultimate tension rating for RR mechanical strength is 70,000 lb. Failure to install within 5° of alignment with the guy load will significantly lower strength.
