Cable Matters [UL Listed] 10-Pack 10Gbps Cat6 Keystone Coupler, RJ45 Keystone Jack Coupler/Ethernet Female to Female Keystone Jack in Black for Patch Panel, Wall Plate

Bought these slighter higher cost couplers based on recommendations and from the fact they are same manufacture as patch panel. Easily installed all 10, just slipped right in and super easy to pop out. Read previous post that couplers were difficult to remove from other manufacture. Did not test these yet as I have to wait to tear network apart and move hardware in rack. Finally installed and these just worked. No failures and so much easier than punch down. They all fit and easy to remove. Will buy more.

Needed to update our work network and I didn't want to buy extra tools for punch down blocks. Plus it is extra work to assemble them myself and there is a good chance I would mess some of them up and have to troubleshoot some bad connections.so I bought these, along with some 100' Cable Matters Cat 6 cables and some keystone jack plates. It all went together quickly and everything worked the first time I powered up the system. Getting all the components (Jacks and Cables) pre-assembled is a little more expensive but it was worth it for me because it was faster and worked the first time.

We switched to keystone versions after some of our older "punch block" connectors started to fail over the years. But they do require a very deep plug box if you are wall mounting them.

Ordered 25 of these to fill up a switch in a smaller 6u rack. Everyone worked perfectly and snapped into place with ease.

When they work they are great. Had 1 that had faults on some of the pins which caused autonegotiate to pick 100Mb and was unable to function at 1Gb. I assumed faulty cable but cables tested fine with tester. Swapped keystone out with another and issue was resolved.Edit: Cable Matters reached out to replace the one that failed. I increased my rating to 4 stars for good customer support.

These are a terrible value, but if you need them, you need them.

Works great, I didn't have any trouble installing these in my existing wall plates. I already had everything I needed to crimp RJ45 cables, so this saved me needing to buy additional tools to work with these. I tested speed on my gigabit network and got great performance so clearly these do their job properly. I was using Cat5E cable so I can't speak to CAT6 specifically but assume it works just the same.

No Issues well built.
