Hi there @anteroal.

Thanks for reaching out and welcome to the community! We’d be glad to help.

Sonos usually refrains from recommending 3rd party products. 

However, some of the community members might provide their own opinion and recommendations about this anytime soon.

You may also check the Port’s product manual for more information.

If you have any questions or concerns,  feel free to reach out.

Personally I just used Duct Tape.

Thanks.  I had seen this product online, and wondered about the quality.  So you don’t actually own it?

As a photographer/filmmaker, duct tape is my go-to for so many things, though ;-)

I do not own that mount.
 

As a really crappy DIY wannabe with zero skills duct tape is my go to for many things too.
