Cable Matters 50-Pack RJ45 Dust Cover, Ethernet Port Cover, Black

You’d think that Ubiquiti would supply rjxx keystone plugs with their pricey switches. No. These do great, like so many other of CM’s products. The plugs have a nice sprue to grab when you want to pull one and free a port. Not ultra pricey and absolutely good enough for keeping dust out

Work exactly how they should. No issues inserting or removing. Fitment is great. Needed to help keep out any dust.

Fit well and are practically invisible.

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

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 for closing the hole.

Excelente

These work well for keeping dust and insects out of the connectors. They fit snug and work well.

Quedan bien en puertos que están al ras pero en los que no están al ras hay que recortarles la parte superior del protector para que entren, tube que recortarlas para que quedarán en un router.
