Reddit reviews RJ45 Jack Snap-in Dust Cover, Inside Jack - 50 Pack

You've based your specs on one brand, which is kind of weird. Normally I'd draft a document so that the specs are compliant to the generic spec (a CAT6 capable jack) as opposed to the vendor specific part (a Gigaspeed X10D part).

I'm OK with Commscope. I don't have any huge complaints about them, and I'm sure their kit is fine. That being said, I'm a huge fan of Leviton and Panduit, depending on the need. For generic cable installations, Leviton cable has never let me down and it's pretty easy to work with.

> Is there anything we can do to mitigate this? Should we just plug a RJ-45 tip into each unused far end jack to reduce how much salt water air is reaching it?

You can buy specific dust covers that should work for the same purpose: https://www.amazon.com/RJ45-JACK-SNAP-COVER-INSIDE/dp/B001S52NX8
