TRUE CABLE Cat6 Keystone Jack, Unshielded (UTP), 90 Degree Punch-Down, PoE++ (4PPoE) 100W, UL Listed, ETL Verified, ANSI/TIA Certified, Modular RJ45 Female, Blue, 12 Pack

I do a lot of network construction and have tried almost every brand of component in the past. Since trying these True Cable jacks I'll never use anything else. It has been said that you get what you pay for and this is a prime example. Yes, they do cost just a little more than some other jacks, but they work every time. A regular punch-down tool will work fine but if you really want to save time and make sure the connection is perfect then do like I did and purchase the True Cable tool designed to punch down all the wires at the same time. The projection between the contacts does an excellent job of separating the wires while keeping the twist in place, making the connections reliable. A plastic locking device ensures the wires won't come loose over time. They are very durable and come in a variety of colors. If you want to save some headaches with your networking, just use these. I highly recommend True Cable for all networking supplies.

These TrueCable keystones are not cheap, but neither are they cheaply made. I'm not a hight volume networker, and only needed to make about 4 dozen keystones so far but each one has tested good. Get a TrueCable crimping tool for best results.

Great jacks, worked from the first try. They fit 3 different wall plates that I tried, so I guess the size and latches are very standard. The grooves are a bit tight for solid copper thick cable, but doable with some effort. Looks good from the outside, too.

Best brand of keystone jacks you can buy period.

Does what it’s supposed to do. It’s sturdy and installation was as expected.
