Recommendation, do not buy. While they could be used for Cat5e, they are pain in the rear to use for the following reasons, A. Cat5E cables go through and through and you may have to pull them back before crimping or use a knife to cut whatever sticks out if you can. B, they do not have channels to allow each wire to smoothly slide into its place, Some wires ended up sliding into other positions and sometimes bend because they are fighting for the same position. I have been doing this for over 5 years so it is not my first time. attached image is for demonstration only (wiring positions inaccurate)
