uxcell Ethernet Hub Port RJ45 Cover Cap Protector Connector 10Pcs Black

This are really great to put in RJ-45 ports to keep dust out. They are soft, easy to install, and remove. Have a device you just want to make sure you dont use the wrong port on? These are good for that too.

Great for my ethernet switches for my security cameras as they tend to be remote (read as dusty) places.

These represent an excellent solution for a very small problem. The rubber dust covers fit snugly into ethernet ports and Im quite comfortable they serve their purpose well (in this case protecting a switch installed into my garage workshop serving networked devices and some ethernet jacks connected through my attic). A tab allows for easy removal.

they fit nicely into everything i have. i ordered more!

Used for plugging failed port. Perfect fit.

Worked great, product was exactly as described.

good

Worked as advertised.

These are perfectly suited for what I was looking for. I had initially ordered the harder plastic ones on Amazon, with the pull tabs on them. I wasnt very happy with those, and had to modify them to actually fit in one of my switches. I had not ordered these as I was hesitant as to how difficult they would be to remove. Once I ordered them, I realized how wrong I was. These are incredibly simple to remove from the port. Im keeping the other ones I ordered to use in a pinch. These will be my go-to port covers.

They plug the hole.
