This particular keystone is good for a shielded cable to terminate network cable runs. The RJ45 jack features gold connectors to prevent corrosion ensuring a longer cable life. They offer a clean transition from a tool less design to a CAT 6A jack for easy deployment in any environment. From the server room/closet to any room in your home or office where network connectivity is desired these keystones are a great option. These Cat6A keystones work with most keystone wall plates, surface mount boxes and keystone patch panels and offer you a highly adaptable modular design.
