These rugged and versatile mounts control vibration and protect against shock. Under normal loading conditions, they exhibit natural frequencies of approximately 25 Hz and isolate disturbing frequencies above 35 Hz. Constructed of zinc plated steel and standard neoprene elastomer (-20^oF to 180^oF) or optional high damped silicone (-80^oF to 300^oF), these fail-safe mounts can be mounted in any orientation.
