8 Pcs Rubber Isolation Pads 1.5 Inch OD 0.5 Inch ID 0.4 Inch Thick Mechanical Vibration Damping Pads Anti Vibration Isolation Pads Vibration Dampening Washer Rubber Isolator Washer(16 Pcs)

I have a sound bar on my first floor that vibrates the walls on the second floor no matter what the volume is at. I also live in a townhouse so I want to be kind to my neighbors. These things seem to totally eliminate the vibrating walls. Sometimes I can still hear the volume but no vibration upstairs/in the walls

Nice, thick rubber washers, just the right durometer for vibration isolation. Put these on top of the vibration isolators, on the outside of the mounting feet, just under the bolt head, with a big fender washer, for that extra mile of vibration isolation. Mr. Heat Pump purrs like a kitten. Can't even tell it's running, inside the house, a foot away. All rubber, all the way.

Ordered these to install under a gas powered air compressor on a flatbed truck when building a tool skid for the hay field. Worked great and really helped isolate the shaking and metal on metal sound.

They are large and thick which meet my criteria. I put them between each layer of my audio rack and then I put speaker spike pad on top of these rubber rings for vibration adsorption; so far so good.

Worked well as a spacer for ventilation on a boat amplifier installation.
