A real pain to wire, and "tooless" isn't accurate.
I used these to terminate 23 gauge STP, which this keystone is recommended for. These were extremely aggravating, and I would definitely choose a different one if I had it to do again. The opening that the wire is fed through to get into the keystone is not really big enough for this wire, so you can't get the insulated blue part under it. I had to feed the twisted wires through by themselves. This prevented me from being able to buckle it down well with the wire tie. Getting the wires into each set of teeth is like pulling teeth. You have to use some sort of tool to get them in. I used a punch tool, and I should have gotten a normal keystone that requires a punch tool. The little lever is a joke as well, and I had to use Channellocks to close the keystone. I did get a bit better after the 3rd one, but I"m glad that was my last one.
Relatively easy to use. I only had to do a handful of jacks so it was fine. They are difficult to close and I ended up using adjustable pliers to close them. I also bought a patch panel that came with a cheap punchdown tool and those were much easier to terminate than these "toolless" ones.
I didn't really care for these. Not really toolless when they send you a small tool to close it which for me was not effective. Keystone's are too wide. These will not fit if you plan on putting them on the plate where they are side by side. I had purchased a plate to put 6 these in one box and I was only able to do 3. Luckily I had some other smaller keystone's like rg6 connector to put along side of them and separate them between 2 boxes. Also with extra wire hanging out they don't look that great. I didn't have anything to trim them off close enough like when using the punch down tool. Next time I will just stick with the punch down ones.
I thought from the description that this would be a relatively easy way to wire an Ethernet connection. The “auto-punch down” concept looked good on paper but I could not make it work. Ended up buying a different connector at a local hardware store that was much easier to do.
