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

Covers the ports well.

Used for plugging failed port. Perfect fit.

Worked as advertised.

They do exactly what you want them to. Made of soft rubber and fit in port well. No excessive overhang, so you can put them in a switch and they dont interfere with surrounding ports.

I needed a way to block staff at the office from plugging into disconnected ports. These did the trick - no more complaints!

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

These things are great. Snug fit, easy to remove, and get the job done. Best plug/dust covers I have ever found.

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.

Recommended, I use it for my home router, laptop, wireless camera.

Perfect Ethernet port covers. Fit snug and stay in! Simple as that!
