MarsMetal
Damper Weights Mars Metal damper weights work to counteract the effects of vibration. Vibration, as perceptible mechanical vibrations can be generated by many sources: Transportation sources such as subways. Heavy truck traffic or streetcars. Machinery in buildings such as HVAC units. People in buildings such as dancing, aerobics, chanting or cheering. Even the wind can cause buildings to sway. These vibrations can generate unwanted structure-borne sound, and in severe cases can cause damage to the structure... (read more)Browse Counterweights Datasheets for MarsMetal -
