They act as dampers and prevent -- Vulcanized to the cover plate damaging shock and rebound. They also act as sound dampers. These mounts are also used as set-up -- Shore hardness A ±5 elements and leveling feet. Medium 55 The parabolic shape of these isolation mounts generates progressive resilience characteristics: Impact • GN 353.2 and shock effects are absorbed more gently.
