Antrader 24 Pcs Silicone Ethernet Hub Port RJ-45 Anti Dust Cover Cap Protector Plug,White

What's to say? They are rubbery and fit nicely into the RJ-45 jacks. Several wall-mounted switches hang vertically via a 19" wall hanger with drop ceiling overheads. I wanted a convenient way to keep dust and dirt out of the ports. Other staff occasionally do maintenance on the overheads; I wanted a way to dust off the crumbs left behind without worrying about debris in the ports. If you, too, find yourself vertically hanging 19" rack-mount equipment, a little protection is a must. It also helps make the installations look a bit more professional.

No more dust in your unused rj-45 ports.

These are brilliant! I didn't know they existed until recently. They keep fist dust out of my switches unused ports while also looking pretty slick. A perfect fit, too. Not too tight, not too loose. They're a rubber material.

Yeah I wished they had nice little handles that make them easier to remove like some of the much higher-priced brands, but these do fit perfectly and there is a little nub that you can grab with fingernails and remove it if need be.

Nice covers, easy to get in and out, keeps dust and little fingers out the ports.

Good for plugging empty ethernet sockets to keep the dust out.

Product worked as expected and was easy to install.

Works as designed, but I wish it fit in better. They're ok, and inexpensive. They keep debris out, as long as they stay in place.
