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

Will save much money & time later by preventing further corrosion in my switch.

Great product!

not much to say, I use them to minimise dust ingress to electronic components since I am based in qatar.

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.

Dropped these into a some of my clients floor jacks to keep them clean of debris and they worked like a champ. Only consideration is that they dont have any sort of nib to pull them out. Perhaps that was intentional. Worked great, would buy again, would recommend these to others..

Product is great with speedy Shipping, Thank you!

They plug the hole.

I like that these work. I dont like that are harder to remove

Bought 30, all fit perfectly. Would recommend them.

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.
