iExcell 25 Pcs Black Ethernet Hub Port RJ45 Anti Dust Cover Cap Protector Plug

Perfect for keeping the elements out of unused router ports. Good product.

Great

These little dust caps are extremely handy to have. I often perform commercial and residential Ethernet network installations where dust over time will become an issue. I use these to cover unused RJ45 ports on patch panels, switches, routers, and unused keystone jacks. They work great. I have not had any trouble with insertion or removal. For folks who have...I have no idea what you could be doing wrong but likely you are tying to FORCE them all the way into the RJ45 port.

I liked them, but depending on the design of your device, it might fit or it might not. For example, on my mac Mini it doesnt fit well, so part of it ends up sticking out. But it does fit precisely on other devices like my Raspberry Pi 2 and 3B+.

GREAT FOR KEEPING DUST OUT OF ETHERNET PORTS.

Nice and handy little plugs; fit snugly but also easy to remove. A little on pricey side for just a little piece of rubber, but do the trick.

I needed to cap off unused Ethernet jacks to keep Leif’s out of them and these work perfectly. Recommend.

These provide a nice tight fit/seal and have plenty of friction to avoid falling out, but are still soft and easy to remove when needed. Excellent product.

Used to seal connectors on an industrial computer

Did what i needed them to do. Simple as that.
