Vibro-Acoustics Grommet Washers (GW) provides a simple way to reduce vibrations and shock loads transferred to support rods and anchor bolts. When used with suspended mechanical and electrical equipment, our Grommet Washers provide a nominal amount of noise isolation. For floor-mounted equipment, pairing Grommet Washers and NEO+ pad isolators can help minimize short-circuiting caused by hold-down bolts and can prevent shock-loading of anchor bolts during earthquakes.
