Terrible product, avoid these. The images say to "use the included lever" which is not included, show a cable guide in the top cover which the product does not have, and show holes for a zip-tie to hold the cable jacket which the product also does not have. Tolerances are sloppy, of the dozen I ordered some fit normally into keystone wall plates, some would barely fit, and others were loose and barely hold in place. I tested them all with the same plate to make sure they were really that bad and the plates were not to blame. They also don't hold RJ45 connectors in properly, cables can pull out enough to lose connection while still fully clipped in. I tested them with multiple known good cables to make sure they were the problem and not the connectors on the cables. These make for extremely unreliable connections and I will need to replace them all.

The big images say to use the included lever tool. No lever tool is included, you have to read the fine print. When you read the fine print, you also see the second problem I discovered. The hinged mechanism is too wide to fit next to another keystone (even if the other one is a standard width). A patch panel full of keystones is supposed to make the rack neater, but now I have to spread all my ports out to double the width and use longer patch cables. Looks worse than it did before.

Unstable, kept loosing connection. Had to replace with regular punch down jack.

I could not punch all the way down, will test it if it works or not

These plugs are garbage. When I punch them down I have connectivity issues and when they eventually work, the male has too much play and often creates issues when the cable moves. I will not be using these anymore.

Total garbage. Do not buy. The connecter is very loose and alway disconnect from male rj45. Endend on the trash.
