Type Yx-1-2xx series spring mounts with two-inch deflection solves critical vibration problems. These mounts are preferred over the one-inch deflection mounts and over most rubber mounts due to their higher static deflection. These mounts are normally recommended for building structures where negligible vibration transmission to the building is required. Yx-1-2xx type spring mounts with two-inch deflection are designed for noise and vibration control applications in critical areas on concrete. Springs have 50% additional travel to max load as per ASHRAE recommendations.
