When working on projects with keystone jacks in racks, I like to use multiple colors to keep different segments of the network clearly separated. These jacks are in a bold green color thats molded into the entire jack, so its easy to distinguish from other ports; theyre also easy to insert and remove.

the products are great and working good, had set them in the rack all connection are working.

Historically, Ive not been a fan of couplers, but Im older now. I might be lazier, but Im definitely less flexible, so my use case was to have patches cables from my server NICs to a keystone patch panel to essentially relocate the ports. The iwillink RJ45 Cat6 Keystone Couplers (yellow, 25-Pack) dont have either of the problems that I always worry about with equipment like this - RJ45s click in tightly, and the keystone clip holds securely. At $18 for 25 pieces (with 10% off coupon, at the time of this review), the iwilllink couplers arent particularly expensive. Recommended

These keystone couplers work just fine. I like to use different color couplers in patch panels to designate different use jacks. They fit just fine in a Cable Matters Keystone patch panel. They are a little tight to insert, but that also means they are secure and dont have any movement and feel secure. I have had no issues with using them with gigabit interfaces plugged into them. They are working great. I recoment these keystone couplers.

I recently received a pack of 25 iwillink RJ45 Cat6 Keystone Couplers and have been very satisfied with their performance. The female to female design made it easy to install and connect my Ethernet cables. The couplers fit securely and there was no wiggle or movement once they were locked in place.

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.

These jacks work well. They look nice and fit well. The performance through the ports seems to be good. I like the shades of green and yellow. They are a bit different to the standard colors.

I have a lot of old cat 5 wiring around my home and as I replace items on the network, sometimes the end of the cable run is not convenient to the new equipment. This connector will solve several of those problems. The cable in photo was previously for a camera and I swapped it for an WIFI access point. To get better coverage, it needed to be two or three feet higher off the ground but the cable would not reach. This coupler has solved that problem, just plug the old cable and the new jumper in to gain that three feet. Signal strength at a camera at an outside building increased about 10 fold with that additional height (it gained height over a building between the access point and camera)

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.

I have these in my basement where I am constantly adjusting where the keystone jacks are installed in the wooden studs, being able to disconnect the keystones and relocate them is very easy.
