iwillink Cat6 Coupler RJ45 Cat6 Shielded Coupler 25-Pack, Ethernet Coupler, Female to Female Cat6 Keystone Jack, STP Keystone Insert Inline Coupler, Silver

Solid keystone couplers that work exactly as expected for high-speed networking. I’m using these in a wall plate for a 10GbE run and they negotiated full speed without drops or errors. The fit is snug, the termination is clean, and they click firmly into standard keystone plates. Build quality feels better than typical no-name couplers, and signal integrity has been excellent so far. Would definitely buy again for structured cabling projects.

Works well, proper fit - easy to install, no issues with connectivity

This coupler was tested and works up to 10GbE connection verified. No issues with connection been in use for nearly 1 month no issues with connectivity it is shielded as advertised. It is a good product although slightly expensive. Have only used as a coupler have not placed any in keystone plates. I will note that my CAT6 coupler also allows for 10GbE connection and they were much cheaper but not shielded so something to keep in mind both items work to provide the same connection so unless you are in a spot where things are critical and need shielding for your jack I would consider these things when making a purchase. But the quality of these seems a bit better than the Cat6 plastic connectors there isn't as much play in the connection. So this to me makes it worth the extra money cause the plastic ones have play which may cause disconnection if pulled or hanging easily solved with some electrical tape or zip ties but still its nice to have a good connection. I will buy again as needed if available.

Just dropping this note to say they do work with 10gbps and support PoE++ since I did not see anyone else mention it. The build is a little on the cheap side, but once they are installed you are not touching them anyway and they look great. I used them with the Ubiquiti Blank Patch Panel, they snapped right in easily.

I got these to replace the keystones currently in use because one tested as bad when I was suspicious about the connection speed light on the switch not as expected. More might also be bad which would explain other slower connection speed lights so I'm replacing all of them. I tested all of these with a cable tester before installing. None were defective. These are physically smaller than what they replace so they are easier to install in a 6 port wall plate than the old ones. The connections are snug. No issues. No complaints. No reservation about recommending them.

Changing my review to 5 stars and apologizing to the vendor: I had ran brand new cat7 cable throughout the house and was having issues sustaining the proper speeds. It initially appeared that the issue was where the cable used the couplers. As I continued to have issues with multiple runs, I realized the couplers were not the issue. Replacing the cable fixed my issues, and I even used the couplers several times to troubleshoot the problem.

Worth it for the price. Has the speed and connectivity it claims it does. It was easy to install on my Ubiquity rack, and the size of the blocks was a little bigger than I thought, but allowed me to connect and disconnect wires from the back with little to no effort.

Excellent product as it does not require messing with cables, just plug the patch cable and move along. I used them to replace my old cat 6 cables.

Wirkt billig – nicht sein Preis wert

These keystone couplers are just what I was looking for. They are easy to install in an ethernet wall plate. Very satisfied.

Good fit. Does what it’s supposed to do! Solid build quality too.

Very good product. Delivered very fast.
