CLEAR STYLE Anti Vibration Pads, Rubber Pads Vibration Absorbing for AC Plastic and Rubber Mounting, Bracket for Outdoor Units Mini Split System Condensers

Excellent for mini split condenser, prevents the vibration , rattling and levels apparatus. So it does move with vibration. My second set I buy. Working great on both units

Actually I'm impressed! Their solidly built for durability. And the rubber pad parts on the top and bottom feet are just right for the job.

Working great so far. They are plastic which was a little scary, but working great so far

These are not heavy rubber vibration dampers. They are hollow hard plastic with about 1/16" of rubber on the bottom. Almost no isolation characteristics. Typical Chinese junk. Poorly engineered (if at all). You would think they could have stolen a better set of plans for manufacturing their products.

Great for lifting the outdoor unit, so the drain line can access the bottom of the compressor. Excellent quality too!

These did not stop the low frequency hum of my small minisplit that was on a shelf connected to the side if my house! The minisplit was vibrating and resonating my entire wall. I did have the bolts too tight. I loosened the bolts, added rubber gaskets which helped. I Ended up replacing these with the fully rubber style. If vibration isn't as critical, these would probably work fine.

First, the actual rubber portion for dampening sounds and vibration is just the very thin layer on top, the rest is all hard plastic. Not as much dampening rubber as what came with the unit.Second, the design makes it impossible to get to the head of the mounting bolt once the AC is mounted, so if that bolt vibrates loose, there's no way to tighten without unmounting the entire AC unit, so huge design flaw. Not at all easy to access even during initial install. If you use a screw instead of a bolt, what you're screwing into is a very thin piece of plastic.Lastly, the design of the base of the units makes it so that you have to use a smaller bolt/screw than would be ideal, and the head room at the top is very tight for tools. I ended up not using mine in the end due to these flaws.

Great product worked great and very easy to install.
