Cup Style Mounts


All-attitude, highly damped mounts for protection of equipment from vibration, shock during steady-state acceleration. Barry B-Mounts provide shock and vibration isolation for avionic equipment in high performance aircraft. They feature low resonant transmissibility and isolate high frequency vibration without snubbing during high "g" maneuvers.
