Review on Universal Keystone Punch Down Tool For Cat6, Cat5E, RJ11 And RJ12 Jacks By IMBAPrice by Robert Ewing

I used to use the tooless (tool less?) keystone jacks, but unfortunately, none of the face plates where I work right now will accept them. So it's either replace every face plate or buy the jacks that fit, which don't come in tooless. I've done many jobs without this innocuous little thing, but I'll never do another one without it. The jacks fit snugly in place and don't move. You can see the side of the jack and the color codes. Its small size is easy to carry around, and if your eyes are as old as mine, easy to manipulate and check your wire positions before punching them down. Would definitely recommend.
