Monoprice Shielded Straight Through Cat6A RJ45 Keystone In-Line Coupler - Silver Use for Networking, Patch Cables, Ethernet Cable/Chord

Works well for attaching 2 short ethernet cables to make 1 longer and functioning ethernet cable. No noticeable data slowdown.

This was purchase in combination with a 20 ft length of CAT5 cable from monoprice. It did not work at all, either the cable or connector were faulty. I was extending my ethernet wire.

7 of 10 Couplers story working after 2-3 years. Long process to troubleshoot. Would not recommend this product.

I'm using these to connect an office computer to a network switch on the other side of the wall. I didn't feel comfortable punching my own jacks, so I got two of these and put keystone plates on opposite sides of the wall, and connected the two couplers with a 1ft Cat6 cable. This was to get wired networking to a home office when Covid hit and we needed a second workspace, and WiFi wasn't going to cut it for constant VPN and video calling. For a time, this worked perfectly. But after a few months, network connectivity became flaky -- sometimes to the point where it was more reliable to connect to the mediocre WiFi than to try to rely on the wired connection coming through these. I tested/replaced each link in the connection between the network switch and the office, swapping in multiple known-good cables and trying different devices, and I eventually narrowed the issue down to these. If you read the reviews for Monoprice's other in-line RJ45 couplers (of the Cat5e and Cat6 varieties) they all have reviews just like mine, where failure seems to be a matter of WHEN, not IF. The other varieties seem not to be direct passthrough connections, but instead connected via circuit boards. I purchased the Cat6a version because they didn't have any such reviews, and I hoped they'd fixed whatever the issue was in the higher-spec version. I haven't pried the Cat6a variety open to compare, but I'm assuming these are the same. I can't fathom why this would be cheaper or easier to produce than simply wiring the connections directly from one side to the other. I have opened an RMA to replace the two I bought. If they fail a second time, I will be looking at other products -- specifically, in-line passthrough RJ45 keystone connectors, which don't use a circuit board.

Should work well. Haven't installed the my intranet yet, that's why only 4 stars.

I ordered a few dozen of these when they were on sale. About ½ of them did not work. The ones that did work were fine.

Tolerance is extremely tight for any inserted RJ45 male end. And for your reference they are a smidge short in port height compared to Leviton They fit a QP jack, but there is a little play.

They work exactly as advertised. And I think you could use these to link two Ethernet cables if needed.

Fit perfectly on the faceplate I purchased. It is basically a coupler that allowed me to wire up a wall with no issues and very fast. I would recommend to a friend.

Couplers were a little slow to arrive, but that was expected with this time of the year. The quality and fit was everything I expected and will not hesitate to order these again. As always, price was very competitive with other suppliers.

These are pricey but you’ll never have to replace them and they perform their job well. I was unable to break them with my usual fumbling around when installing into a Keystone panel. Usually with other brands, I break at least one during installation

I should have used a traditional or tool less keystone but at the time of order seemed like a good option for the install. It works well.

Extremely satisfied with this product, great connection extender.

So far they've worked as expected. Hopefully they have good longevity.

Terrible product - they loosened up over time and eventually failed completely - the Cat 5e version is the same product with a Cat6 label.

My Monoprice 8P8C RJ45 Cat5e Inline Coupler Type Keystone Jacks are exactly what I needed and work fiine!

This works well, but with that being said you'd think buying the face plates from monoprice everything would fit into place but they will not snap i place. For this reason I gave this 3 stars. So beware.

Product works as intended. We have had no issues while installing.

These worked perfectly with the Keystone plate sold on Monoprice.

Handy device but not sure why these include a circuit board in between the contact wires. Agree with reviews that these are great when they work, but have a high failure rate (mine died unexpectedly after about a year or two. Not recommended for professional install. Will be switching to a non-interrupted in-line connector (no circuit board) next time.
