iwillink Cat6 RJ45 Keystone Jack Coupler, Female to Female UTP Keystone Inline Coupler, 10-Pack Black

dis iz a tool. it not from amazon but purchased from amazon and it was shipped well really it wuz driven by truck then carried buy a human to the destination that it was to be delivered den placed into a locker that could securely hold it being it was a metal locker that was blue and had writing on the outside and used an electronic locking mechanism to open kinda like magic.

I have several female Ethernet connections in the wall, and needed to color code them to separate out the devices they go to. I originally did this to clean up a cable mess, but couldn't remember which connection was which. Putting in these with two other colors solved the problem.

Works well and good quality

These Keystones feel like quality keystones. The other ones I have feel like hollow plastic, where these feel like solid plastic. Very sturdy and have been functioning well too.

These keystone couplers work as expected and were painless to install. Color was consistent across all three packs I bought (two ten-packs and a five-pack) and I didn't have any trouble removing and reinstalling them.

Easy to use and extend my network cable inside my chassis.

I'm not sure, exactly, why these are referred to as "Cat6 couplers." Cat 6 (or 5, or 7, or 8, or...) refers to the construction of the CABLE, not of the terminators. Yes, Cat 7 generally uses a different connector, not the RJ45 that this uses, but still, any cable which uses an RJ45 modular connector ought to work equally well with this. There's nothing here "unique" to Cat6.Of course, Cat6 ethernet cable is the most commonly used home networking cable at present, do if you're wiring your home, this is a great option. Whether you're doing "Cat5," "Cat 6," or "Cat8."I suppose the hypothetical "Cat8 couplers" (which I've personally never seen) might be better shielded, but the need for shielding over a very short length like what's in this is trivial. The longer the "antenna," the more the need for shielding.These are "Keystone" couplers. This means that they are designed to install into panels, not to go in-line, though they CAN be used in-line, I suppose. Rather, they're designed to go into racked equipment panels, or even into the little "gang box cover plates" we use to wire up our homes for electricity, or telephone, or cable, or the like. There are plenty of "keystone" network port gang-box covers, and this is how I intend to use these.So, my home setup is as follows: My cable goes to my modem. It is then connected, by Cat8 cable, to my router. The router then goes to my home server, also by Cat8 cable. (Neither device actually supports Cat8 speeds, mind you, but I like the additional shielding performance for those locations, and the connections are pretty short, so I can justify the higher cost of Cat8 cable.) The router then also goes to my work PC, and then to an 18-port unmanaged switch (which also injects "power over ethernet"... aka "PoE.") This, then, goes throughout my entire home, to (at present) a dozen termination points... at least one in each main room, plus several for security cameras.I'm using these for the drops in each major room. Installing new gang-boxes, dropping terminated Cat6e ethernet cables down the walls to those boxes, plugging them into the rear of these connectors, and then plugging my in-room hardware into the front of the wall plate. And I still have six potential added termination points I can add if I need more in the future.In which case, I'll need to buy more of these, plus more installable gang boxes and cover plates, of course.It's working out very well so far, though... and these (or similar devices) are a central part of how to do that.Are these better than others on the market? I can't say. I doubt it. There's not a lot of difference you can make from one such "commodity" device to the next. But these do everything I need them to do, and I'm happy as a result.

These should be simple to manufacture, but they aren’t all to spec for the keystone opening. Some didn’t fit. More importantly, half had cracked clips when they arrived. Others broke trying to slide them into the panel. Every other brand of punched or pass through terminal will go in and out easily, but these are so brittle (and apparently not quite the right size) that they just keep breaking. Save yourself some trouble and buy a different brand.Edit: in just a few months I have had more than one stop testing good for gigabit links. I’m only able to negotiate 100 megabit through some of these.
