S-MOUNT SERIES

Low-frequency variable air-damped mounts for a high level of vibration isolation. Barry S-Mounts are air-damped isolators and are designed to provide the highest degree of vibration isolation for sensitive commercial and military airborne equipment. S-Mounts are particularly effective at isolating low level vibration.
