Very happy with this purchase. They seem beefy and significantly reduced the vibration of the garage door opener to the upper floor. A++++!!!

These work, noise is reduced to almost nothing at the bedroom above the garage.You are suspending a heavy vibrating motor on rubber isolators that are installed on shear so please be careful. They may pop out if not supported. After I installed 2, the isolators twisted and since they are just compressed rubber at the mounting bolts, over tightening them will shear off the rubber. I added a diagonal brace to each side of the opener to install 4 instead of 2 isolators. The 4 isolators made the install much more stable (no more twisting) and they can handle the weight of the motor long term. I added 1.5” X 5/8” washers to both sides of the isolators to help the bolts inside press against the rubber. I added locking washers to prevent the nuts from unscrewing without over tightening. And lastly I added a rubber bungee cord to help take some of the load off the isolators and provide extra insurance. To reduce the noise inside the garage I installed Noico (same as Dynamat) inside the opener housing.

Just did the installation of these isolators on my garage door openers, and the process is fairly straightforward. If you remove the old brackets with the opener supported with a ladder, then add the isolators, and adjust the brackets to brace the isolators to the opener, the common complaints listed by others become a non-issue. This is because the isolator and bolts are effectively pins to keep the opener elevated (no through bolt required). I agree threadlock doesn’t hurt here, but frankly a second nut is just as effective.Noise level of my garage doors are cut by more than half… so not dead quiet but significantly more tolerable.

My rating is mostly for the effectiveness in reducing noise in our nursery above the garage. The sound of the garage door opening is now very subtle. I was very reluctant that these would work well. I assumed there was a single bolt that went through the bushing and it would still transfer vibration, but the rubber bushing does a great job isolating the vibration.I noticed a lot of reviews complaining about the nuts coming loose. Just use Loctite or replace the nuts with nylon lock nuts.Bottom line: they work and they're worth a try for the price.

I was excited to have found these to reduce the noise of the garage door opener. Sad to say these things are not meant for a door motor. They sag from the beginning. It did reduce the noise heard in the house a bit. One of them fell apart after one week, found my opener dangling. Can you imagine if the others gave and it fell on the car or on the kids?!

Installed these on both of my garage door motor mounts. Measured the decibel level before and after and not much difference. But, did seem to reduce the vibration on the floor above the garage doors. Eventually replaced the steel wheels with the vinyl ones and that helped with vibration too. Still not as quiet but doesn’t shake my bed and wake me up like it used to.

I had a motor mounted on a steel frame with an electrical breaker box, and the box rattled something fierce when the motor was running. There were even shock pads beneath the motor, but the bolts ran all the way through the pads and were transferring vibration from the motor to the electrical box, causing the rattle. When I installed these isolator mounts the rattle completely stopped and the motor went back to a gentle hum. Installation took about 10 minutes with a small combination wrench. The nuts and washers came with the mounts. The studs on the mounts were 8 mm, which is almost exactly 5/16", which was the size of the bolts I replaced. Overall, I was amazed at the difference it made by getting an isolator mount that did NOT have a through stud.
