I need a cover or something for a few of our standard wall plates so we can lock down the jacks. We have some desks wired up with phone/ethernet connections and they connect directly to the drops. Clients come in and remove the cables from the jacks and connect their own laptops, even though the plates are labeled DO NOT TOUCH. Does anyone know of a cover that would prevent access to the jacks? I want to plug the cables in, then cover it up so they can't remove them.
