Keystone jacks are standardized, removable connectors that fit into keystone wall plates, patch panels, or surface mount boxes. They are designed to accommodate various types of cables, such as Ethernet (Cat5e, Cat6, Cat6a, Cat7) and telephone cables. Keystone jacks provide a full range of termination solutions for voice, home networking, home office, audio/video and more. Cat6/6A field termination/modular plugs are modular connectors that can be attached to the ends of Cat6/6A cables to create ethernet connections by terminating the cables directly on-site.
