What it is: 25 pack of green and 25 pack of red low profile Cat6 coupler jacks.

Simple and does the job. Used for existing wires that were already terminated with jacks to add them to a patch panel so all connections and wiring going forward would be uniform. These seem like a good-quality build and Ive had no issues with them so far.

it comes with a good amount. they not cheaply made and work well.

The iwillink RJ45 Cat6 Keystone Coupler 25-Pack is an excellent choice for anyone looking to simplify their network connections. These female to female Cat6 Keystone Jacks are designed for use with UTP Keystone plates and panels, making it easy to add or remove network connections as needed.

The iwillink RJ45 CAT6 keystone jack couplers are a perfect addition for my patch panel, I was able to color code different segments of the network using the various colors of the jacks. The jacks fit very well into the receiving end of the keystone connection on the patch panel and locked in very tightly.

Im in the process of tidying up the cables in my house. I thought this would make the job easier since I wouldnt have to splice any cables. This works perfectly. Im able to plug the source cable into one end and the destination cable into the other. I tested my bandwidth and didnt notice any drop in performance. There are 25 jacks which are more than enough for my house. I love how these include zipper bags so I can keep track of the extras.

This worked well for patch cable so you dont have to terminate the lines right at your network box. You could just run regular cords all the way up to it and just have it pass through. So if you ever needed to change out the line, you didnt have to do a whole bunch of additional work. Just plug and play.

These worked fine in my tests to connect two Ethernet patch cables and were compatible with my wall plates and patch panels.

This is one of many iwillink networking products that Ive ordered and reviewed. As always Im impressed with the quality of their products. These keystones arrived well packaged. They feel well built and sturdy.

Good ethernet couplers for Cat 5/6 cables.
