Great for universal patch panels for those single cables run that are not terminated on the patch panel. I use these for the Ubiquity Cloud controller hidden behind the patch panel to prevent the "whatsthis" questions.
Keystone Jacks and Wall Plates for Keystone, 2 Hole
I ordered Modular F type and Cat5e keystone jacks in white and black, but only find/buy the white 2 hole wall plate. I had to buy the black wall plate elsewhere. This cost me a higher price for the wall plate, plus shipping to another supplier. If your going to sell the jacks, then sell the matching plates.
PROS: Everything installed easily and is working well.
CONS: Had to buy the Black wall plate from another supplier increasing my overall cost for project.
