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

These fit snugly and stay in place. Very nice. It would be nice if they had other colors - such as red. Since they are all black you cannot easily see that an ethernet port has one in it. I use these because my product has two ethernet ports and I want my customers to use the left one first (they rarely need to use the second one). By putting one of these in the right one it prevents them from plugging their network cable into it. Unfortunately they still try because it is black and you cant easily tell its a rubber plug. A red one would solve this problem. Still - this is a good item and I highly recommend it. There are others out there, but the other one I tried will just fall out under its own weight.

Fit perfectly in Ethernet ports.

Very useful for unused Ethernet cable outlets, easy to apply it on

I had my whole house wired for ethernet, but havent plugged something into all of the jacks, so I bought these for any empty jacks. Works great, good buy.

Short and sweet. These are simple rubber dust covers. They don’t snap in but they are easy to place and fit snuggly in the ports.

Awesome! Not sure I like them in black. Little hard to tell theyre in. But they work great. exactly what i was looking for.

Easy, perfect, zero complaints! Does the job as designed.

They fit great on my ether net port. Very high quality ethernet cover port/cap. I highly recommend it.

These work well but you need to be careful inserting them. It’s very easy to insert them too far making it difficult to remove them. They are very soft and pliable. A harder plastic rather than soft rubber might have been better. They will do the job though.

I have couple cisco 24 ports switches, I have to clean the ports regularly to avoid the dust build up, the cap fits perfectly, and I dont have to worry about the ports any more!
