The Phosphor Bronze termination contacts will stand up to multiple punches while the Keystone Jacks as a whole meet or exceed the industry standard TIA/EIA 568-B. Color coding and quick identification just got a whole lot easier.

Labeled with both 568-A and 568-B color codes there will be no more memorizing color codes.
