Sorbothane vibration isolator pads are versitile anti-vibration pads that can be used as feet, stops, spacers and protectors in many different applications. The unique Sorbothane urethane is a durable, resilient, polymer that provides outstanding vibration isolation and non-skid properties. Sorbothane isolators help absorb impact and noise and have excellent resistance to aging; they will not harden or crack over time. They feature a smooth, clean, black urethane surface. Use them on any audio and electronic equipment to prevent skipping and interference.
