Black Box Corporation CAT6J-BK-25PAK wired accessory

SKU CH-65ZB-9CF3A MPN CAT6J-BK-25PAK

A pack of 25 black keystone jacks with gold-plated RJ-45 contacts for Cat6 network connections

  • Product colorBlack
  • 25 keystone jacks in one pack simplify large installs
  • Gold-plated contacts resist corrosion for reliable signal transfer
  • CAT6-rated connectors support gigabit Ethernet speeds
  • RoHS-compliant construction meets environmental standards
  • Black finish blends cleanly with standard patch panels

25-Pack CAT6 Keystone Jacks

This 25-pack supplies black CAT6 keystone jacks with gold-plated contacts for terminating network cables in patch panels or wall plates. The value line keeps cost low while meeting RoHS compliance. Each jack presents an RJ-45 female connector suited to standard keystone openings.

Ideal for bulk installs, not single runs

Installers wiring multiple drops in offices, schools or home labs will appreciate the per-unit savings of a 25-pack. Anyone needing only one or two terminations should consider smaller quantities to avoid unused stock.

Gold-plated RJ-45 contacts

The gold plating on the RJ-45 contacts resists oxidation and maintains reliable signal integrity over repeated insertions, which is the key spec distinguishing these jacks from unplated alternatives.

Questions about this item

What do I need to connect to the 25 RJ-45 female keystone jacks in this pack?

You need Cat6 or compatible solid-core network cable to punch down into each jack, plus a keystone-compatible wall plate or patch panel to mount them.

Will these black Cat6 jacks work with my existing Cat5e patch cables?

Yes, the RJ-45 female ports accept standard Cat5e plugs, so older cables will connect and run at Cat5e speeds.

How can I verify each of the 25 jacks is terminated correctly after installation?

Use a cable certifier or continuity tester on every run; a full wire-map pass confirms each gold-plated contact is seated properly.
