These are the first keystones I have worked with and overall my first ever job in cable termination for a patch panel. I found the process easy and quite fast. They have a guide in which you insert the cables (according to the standard you want - T568A or T568B) and it guides you with colors on how to do it. The guide simply holds the cables and does not require a special tool, it can be done easily by hand. Afterwards, you simply press firmly the guide onto the keystone slot. You cut off any excess. You close and secure it with a tire up. The packaging also includes a small white tire up. Overall, they are sturdy construction made of some metal and fit perfectly in the Logilink patch panel I purchased for this purpose.
