SFP-B SFP Port Dust Cover Ethernet Protectors Anti-Dust Cover Caps Plugs for Ethernet Hub Slot, Black Silicone, 14x12x17mm, 20pcs

These nice silicone RJ45 Ethernet Port Plugs fit snuggly and securely into my empty ethernet ports on my switches and patch panel keystones. Great product at a great price.

good price, really useful !!! used mark which MAC address has already been seen on the network and which ports are not to be used.

These can be a pain to get in the port but they do the job and they don't seem to fall out. I put these in all my FC & ethernet optical ports not populated with a SFP+.

Aside from the wrong item description (-1 star). These are good sillicoln dust covers for LC connectors. They have a good handle for insersion and removal. They are soft silicoln so they don't scratch the fiber ends. Overall good. Would give the star back if I didn't have to search so hard to find them. (Correct the name, please)

Great little inserts, will extend the life of your switch & eliminate surprises when plugging new wires to ports that were unused for long. Well with the investment!

Do you really care your plugs are silver and match your silver unifi gear? I don't! These are significantly cheaper than the super expensive ones from Ubiquity. They work exactly the same but you get way more in the packaging. Really these work just fine.

These are great for protecting unused switch ports, especially if it is an area with more dust that gets kicked up. They are flexible, soft and fit perfectly.

I like these because it keeps dust out of unused ports. Love em
