Sorbothane Premium Vibration Isolation Washer (1.75" OD x 0.63" ID x 0.25" Thick, 30 Durometer (Soft))

Excellent product, I used them under a CD Player that was in close proximity to large speakers. What I really like is the more you tighten the mounting screws the denser they become. If that does work, loosen the screw to make them more spongy. I would definitely buy again.

These are amazing. Very soft and pliable just as described.

I am very skeptical that the 50 durometer washer can hold the capacity that they claim. These things are squishy. Anything heavy like a speaker I would definitely go for the 70. This Amazon product listing needs to have the full chart that shows the weight capacity, and needs to indicate if the rating is for a single washer or all 4. The listing also doesn't do a very good job of making it clear that this is for 4 washers, that needs to be in the title.

We use these as gaskets for our bottle-filling machine, which work well.Perfect Durometer and size.

I have an expensive high power telescope and wanted these under the tripod legs to dampen the vibrations. I was unsure the "50 duro" in the . 5" thickness would be enough to support the weight (maybe 50#s) without giggling, but it works superbly.I attached these to "furniture glides" mostly to give a firmer top so the pointy tripod legs wouldn't just sink in with these sorbothane washers toward the ground. I have tried all sorts of combinations over the years including items made specifically for telescopes. These are functionally far far superior.
