iExcell 25 Pcs Black Ethernet Hub Port RJ45 Anti Dust Cover Cap Protector Plug

These work great in my 24 port switch. They fit the slots perfectly.

These fit snugly and stay in place. Very nice. It would be nice if they had other colors - such as red. Since they are all black you cannot easily see that an ethernet port has one in it. I use these because my product has two ethernet ports and I want my customers to use the left one first (they rarely need to use the second one). By putting one of these in the right one it prevents them from plugging their network cable into it. Unfortunately they still try because it is black and you cant easily tell its a rubber plug. A red one would solve this problem. Still - this is a good item and I highly recommend it. There are others out there, but the other one I tried will just fall out under its own weight.

These provide a nice tight fit/seal and have plenty of friction to avoid falling out, but are still soft and easy to remove when needed. Excellent product.

They fit perfectly and are well made. Im very happy with my purchase.

Fits perfectly on both my tplink and treadnet switch

Perfect for keeping the elements out of unused router ports. Good product.

They work well,had no problems installing or removing from ports.

Easy way to protect your equipment.
