iExcell 100 Pcs Black Ethernet Hub Port RJ45 Anti Dust Cover Cap Protector Plug

Sticks in the ethernet ports plenty secure. Perfectly good snug fit. Won't fall out. Protects your vertical mount switches from cable trimmings and other debris from falling in the ethernet ports. I'll buy more for our vertical switch mount installs. Those complaining of these being difficult to remove must not have any experience with port covers. You want them to stay in secure. And these are not hard to remove at all. Lift up the lip and they pop right out just like they are supposed to. But they also stay in like they are supposed to too.

Works as designed and comes in a little plastic box. Easy to insert and remove and a must have for networking OCD.

Works great for a rack enclosure. A good extra layer of protection for dust during construction and future proofing.

I have had so many different expensive tire air caps on my car that have gotten stolen over the years. 125 pieces in this pack is a lifetime worth of air caps just in case anyone should steal them off any of my vehicles. They fit just right without letting any air seep out of the tire when tightened all the way. They do look cheap, but at least they are the color black so from a distance you cannot tell how inexpensive they were. They work and that is good enough for me.

It's a soft plug for unused switch/router ports. They work fine...easy to insert and easy to remove and will keep the dust out of the ports. Not much more to say.
