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.
