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

They work well,had no problems installing or removing from ports.

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.

Not sure what else to say! They fit! Just dont lose them when you take them out! Ive lost a few already because of my own negligence.

Used on a switch which is mounted near our ceiling. These keep the dust out of the ports nicely.

Used to seal connectors on an industrial computer

Used these for a switch and patch panel and they fit perfectly. They are easy to fit and remove, when needed.

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!

these are great rj45 port dust covers. they dont get stuck on the wires if accidentally pushed too far in, and easy to remove.

Fit perfectly in Ethernet ports.

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+.
