AFL Highway Truss Dampers offer the most practical and economical solution for vibration problems normally encountered in highway sign trusses. The AFL 1708-17.1 damper, weighing 31 lbs. (14.06 kg), is the size most commonly used for highway truss applications. A single damper located at the mid-point of the truss will provide vibration protection for lengths between 60 and 140ft (18.3-42.7m). Special consideration should be given to longer spans or cantilever applications.
