The RJ45 CAT 5e patch panel is 19 inch rack mountable and supports both 568A and 568B installations. Compatible with 110 punchdown tools, this Patch Panel’s front-loading modular design makes termination, upgrading and trouble-shooting easy at any location and any position. The snap-in modular design is also perfect for tight space application because you no longer have to terminate it behind the rack, everything can be done at the front of the rack.
