I was looking for a way to run one of my ethernet cables through the wall into an existing multifunction outlet in the next room. This Keystone CAT6 jack was just what I needed! It fits easily but securely into an empty slot on the exit panel (satisfactory locking). I could then just plug the shorter CAT6 cable into the other (wall) end and voila, done. There is no need to laboriously rewire many signal wires in a normal Ethernet cable β a job that is probably beyond my talent and experience anyway. I'm so glad Revain is wearing this Line Jack.
