Cable Matters 50-Pack RJ45 Dust Cover, Ethernet Port Cover, Cat 6 RJ45 Anti-Dust Covers for Patch Panel, Network Switches, Routers, Server Racks, Computers, Black

Excellent RJ45 port covers. Highly recommended as a way to protect the unused ports on your equipment. Perfect functionality. Excellent value for the money. These covers are much better than others I have used. Theses are made of a stiff silicone like material. They have just enough flex so that they fit in snuggly into empty ports. They do not fall out. I have them in a switch mounted high on a wall with the ports facing down, and these covers stay put, even upside down. The circular nub makes them easy to grab and remove, or insert. Even if there are cables in the ports to the left, right, and below the empty port. Many of the competitor covers are flat against the face of the port when inserted, lacking the "handle" nub these have. And while one might argue those flat ones look nicer, they can be a real pain to remove, even when not surrounded by cables of in use neighboring ports. And they are nearly impossible to remove when all the ports around them are in use, especially if you have big hands. Same if you are trying to install those flat ones. I even had one of those flat ones, that was made of really soft silicone, fold up and slide into the port rather than covering it. I had to remove it with tweezers and worried about port damage. These Cable Matter ones however could never fold up like that, and they are so easy to grab and remove or insert. Don't underestimate that as a significant feature.

Great quality and great fit! Also looks good on switches in rack and looks clean.

Easy to install or remove, they fit perfectly in a Ubiquity switch and look good while keeping dust out. I haven’t had any fall out after several months so they seem to stay put relatively well even though they don’t clip in.

works well - fit snug

Great for closing the hole.
