PoyiccotRJ45 Breakout, RJ45 Screw Terminal Adaptor Connector, 2-Pack 8p8c Female Jack to 8 Pin Screw Terminal Connector for Cat7 Cat6 Cat5 Cat5e Ethernet Extender CCTV Digital DVR Network Adapter

So it drives you nuts when you are wanting to see if you have continuity on one of those pins, or a pin shorted, whatever, but your multimeter leads aren't slim enough to contact those fine little pins. Just plug the RJ into this adapter and use your multimeter leads on the break-out screws. Works great! Not enough for you? You can also use this to make a loopback test plug for T1 or ethernet or any other kind of connection. And because it has screw terminals, you can change it around any time. Very handy adapter!

Great for projects

I ordered six (total) of these for a wire harness conversion on my 3D printer to CAT6. I initially started with push-down keystones, but the typical wire gauge on my printer (18-20awg) was too large for the keystones and was damaging the terminals.I checked each contact to ensure that there was no issue with shorting, and they seem fine. I also checked the pin orientation, because I've found several different pin orientations for 8P8C screw terminals online:The leftmost pin is Pin 1, and the rest of the pins are sequentially arranged (left to right: 1, 2, 3, 4, 5, 6, 7, 8). This pin orientation is the same on either side; that is, you don't need to mirror the cables if you're using a normal ethernet patch cable. However, if you are using a crossover cable, you WILL need to mirror their orientation. Research patch vs. crossover cable if you aren't sure what this means. If you have a standard, generic, pre-terminated ethernet cable, it is most likely a patch cable.The screw terminal hub on each connector is able to be removed and re-inserted, thus making the terminals modular. Each terminal also has a patch of textured plastic on either side which is great for writing marks with a permanent marker (I use it for a reference mark to determine which terminals match together, as each side of my wire harness uses three identical terminals).Overall: much more expensive than generic RJ45 keystones, but also more rugged, modular, and will accept larger wire gauges than push-down keystones allow for. I'm happy with them.

My apologies for the previous review, these work fine, the problems I had were with the dual rj45 connectors.
