Information

Vibration Dampers work to cancel damaging fatigue caused by wind-induced vibration.Most tuned damping devices operate best near their natural frequencies. vibration dampers are designed for efficient transfer and dissipation of energy over a wide spec_x005ftrum of frequencies. They feature all aluminum clamp construction to match expansion/contraction of conductor and break-away bolts for easy installation and proper torque.
