ANTI-VIBRATION GROMMETS
Anti-vibration grommets are designed for noise suppression in office or lab equipment. Additionally,
they isolate sensitive instrumentation from unpredictable vibration and shock. The fingers of the grommets
provide the flex needed to dampen unwanted noise and vibration. Specially designed shoulder screws
are designed to provide the correct spacing.
