High Deflection Mounts


Low-frequency, highly damped mounts for high level shock and vibration isolation. Barry HTTA-Series Mounts are low frequency isolators with a large deflection capacity to provide both Vibration and shock protection. They are designed to meet the requirements of MIL-STD-810C for mounting electronic equipment in helicopter environments.
