►Feature: 1. Mainly used with an inertial base as an open-type spring mount. 2. Used for equipment that needs maximum isolation. 3. Heavy-duty vibration isolation. 4. Easy to install, allows easy inspection since the spring deflection can be visually checked. 5. Isolators have a min. operating Kx/Kz ratio of 0.8. 6. Spring has additional 50% actual deflection.
