ROHN's R-TB25D torque bar is recommended for use with the Rohn R-GA25GD standard guy bracket at guying locations near microwave and other focused-beam antennas to provide added resistance to torsional movement of the tower. Three (3) bars are needed to modify a standard guy bracket into a torque-stabilized assembly that can be installed at any existing guy attachments on any horizontal brace. Each torque bar requires a 3/8 in shackle to complete the upgrade.
