The Black Box GigaBase2 CAT5e Jack in a bright yellow finish is built for reliable, scalable network terminations across enterprise, data-center, and home-office environments. This 25-pack of high-performance keystone jacks is designed to deliver fast, consistent terminations with industry-standard CAT5e capabilities. With universal wiring, a user-friendly 110 tooling interface, and materials chosen for durability, these jacks help you deploy clean, organized networks that stand up to daily use. The color-coded yellow jacks are ideal for quick identification in crowded patch panels and wall plates, reducing installation time and minimizing wiring mistakes.

  • Universal wiring for T568A and T568B: The jack is clearly labeled to support both wiring schemes, enabling seamless compatibility across different network layouts, contractors, and equipment in mixed environments. This flexibility significantly reduces rework when upgrading or expanding networks, and it is especially valuable in patch panels, wall plates, and data centers where multiple standards may coexist.
  • High-quality IDC contacts: IDC contacts are made from phosphor bronze with tin plating, delivering dependable contact reliability and solid signal integrity over many terminations. This combination provides robust insertion force, low contact resistance, and long-term performance in dense installations where connections may be made and remade repeatedly.
  • Gold-plated nose contacts for superior durability: Nose contacts feature 50-micron gold plating over a 100-micron nickel underplating. The gold layer resists corrosion and wear, helping maintain signal quality in high-density environments and extending the life of the jack through repeated terminations and terminations reassignments.
  • Easy terminations with a 110 tool: Designed for fast, dependable terminations using a standard 110 punch-down tool. The precise contact alignment and snug fit help ensure clean, repeatable terminations, reducing install time and operator fatigue on large-scale deployments.
  • Strain relief with termination retention cap and visibility: The termination retention stuffer cap provides reliable strain relief to keep conductors securely in place. The bright yellow color helps with quick identification in racks and panels, enabling efficient testing, troubleshooting, and future rework when needed.

how to install Black Box GigaBase2 CAT5e Jack

  • Prepare the cable by stripping back the outer jacket and exposing the twisted pairs without nicking the copper conductors. Leave enough insulation to insert fully into the IDC contacts. Maintain the twist length close to the termination point to preserve signal integrity.
  • Choose the wiring scheme (T568A or T568B) based on the rest of the network, and align the color-coded pairs with the jack’s printed guide. The universal wiring labeling on the jack helps ensure you place each conductor in the correct slot.
  • Insert each conductor into its corresponding IDC slot with steady pressure. Use a standard 110 punch-down tool to drive the conductors firmly into the contacts until the stuffer cap is seated and the wires are captured securely.
  • Engage the termination retention stuffer cap to provide strain relief. This cap locks the conductors in place, preventing movement that could degrade the connection over time and with network activity.
  • Inspect the termination visually for any loose strands or misaligned wires. If available, test with a cable tester to verify correct pinout and continuity before mounting the jack in a patch panel, wall plate, or surface-mounted faceplate.

Frequently asked questions

  • Q: What does universal wiring mean for this CAT5e jack? A: Universal wiring means the jack supports both T568A and T568B wiring schemes, and it’s labeled to guide the user to terminate wires correctly in either configuration. This makes it versatile for diverse network environments and simplifies upgrades or reconfigurations.
  • Q: How many jacks are in a pack? A: This product is sold as a 25-pack, offering bulk convenience for large installations, multi-port patches, and consistent color-coding across panels and racks.
  • Q: Why is gold plating on the nose contacts important? A: Gold plating reduces oxidation and wear, helping to maintain low contact resistance and stable signal integrity over time, especially in high-density terminations and frequent re-terminations.
  • Q: What tool do I need to terminate these jacks? A: A standard 110 punch-down tool is recommended for clean, reliable terminations with the IDC contacts on these jacks.
  • Q: Is yellow color coding significant? A: Yes. The yellow color helps with quick visual identification in crowded panels, making it easier to manage cable runs, perform testing, and rework without confusion.

Approved by an Overnight Registered Nurse, Has worked great last 4 years!
Item Package Quantity: 1, Size: 100 Count (Pack of 1)
I have worked overnight as a Registered Nurse for the last 4 of 6 years and I will offer my own experience on how these pills have helped me in my job performance. To start of with I have to say that no two human beings are the same so before I bought these pills I read the good and bad reviews and wasn't sure on the product. I've had heart palpitations in the past from excess caffeine when I drank one of the blue pop top Rock Stars with 1.5 times the caffeine as regular Rock Star and I can say that no, it's not fun at all. I've also experienced when I drink to much caffeine at once and find myself either visiting the restroom many times during a shift, or the crash that comes after the initial burst of energy. Anyways, I can say that with ONE pill a shift prior to going to work, I am able to stay awake and not in a forceful manner without the many negative effects from caffeine that I've experienced in the past. Working night shifts, I've seen how many co-workers need to chain drink coffee all night. I can't say that I don't like coffee, but I don't drink it more than once a week and I prefer not too if I have the chance. This is why I am glad that the Guarana Energizer has worked for me. I am able to be more alert all shift long, not have to struggle with energy or struggle with staying awake, and when I get home I not too wired where I have a hard time going to sleep. On my days off it also works as an excellent energy booster for the mornings to get your energy level going for your day ahead. Also, I've tried other guarana pills when the Source Naturals were no longer in stock (same 900 mg strength), and I have to say that I had to take more than 2 pills per shift to keep me awake, plus they never lasted a full shift. Don't know why the "energizer" term makes a difference, but it does for me. I recommend it to all my co-workers, and when they feel low on energy I've seen that even 1/2 a tab is sufficient for a little pick me up especially for those sensitive to caffeine.

The best guarana I've used - helped me kick energy drinks!
Item Package Quantity: 1, Size: 100 Count (Pack of 1)
I suppose I ought to stand in front of a group of people, and admit to being a caffeine addict. However, I rather like caffeine. I started in on caffeine at an early age- first by drinking soda- mostly cola- as often as my parents would allow. As a teenager, I discovered coffee. Later, it was espresso drinks- I loved a good quad-shot latte, and eventually was getting several a day. A few years ago, my stomach stopped agreeing with coffee as much, so I switched to energy drinks. I was drinking about 4 Rockstars a day. After doing the math, I realized that I was spending around $300 a month on these silly beverages. To economize, I switched to No-Doz. However, it wasn't the same, and it honestly felt... unnatural. The No-Doz sometimes aggravated my stomach, and I just didn't feel as well. Then I tried Guarana, as it is one of the main functional ingredients in many energy drinks. Love it. It seems to last a bit longer (it could be my imagination there, I am unsure), and it definitely feels more natural. I take a few of these per day- and I seem to have less of a "caffeine crash" after 4 hours or so than I once did. It still happens, but it's more gentle. My only complaint is that the pills are rather large- definitely a chore to swallow! Bottom line- this stuff costs just a bit more than a bottle of No-Doz, and is made from natural stuff. It feels healthier, and probably is. I now spend in a month wha I spent in a day on energy drinks. Also- for what it's worth- I've tried other brands of guarana, and this one "feels" best.

Worked well for a few days, then built up a tolerance
Item Package Quantity: 1, Size: 100 Count (Pack of 1)
Guarana for me is one of those things that you should only take every once and a while. It gave me a nice surge of energy for about an hour or so after taking one, then after only a few mornings of taking one I noticed the effect completely wore off. So I stopped taking it for about a week. Then tried taking it again and it still did nothing. Maybe it's just my body, but now I need at least two to notice any effect. It's not that I even feel more alert now, it just makes me feel like I drank to much coffee. I will finish the bottle and then will not buy it again. Different supplements work differently for everyone though! Just because this didn't work for me longterm, that's not to say it won't work wonderfully for you. Trial and error is key with anything like this.

Great substitute for Adderall.
Item Package Quantity: 1, Size: 100 Count (Pack of 1)
This is a great supplement to have around, especially because it's SO easy and economical compared to coffee. I would happily rate it 5 stars BUT I have to admit that the first few times I took it, the jitters it gave me were pretty extreme. It didn't bother me AT ALL, but I know that it would be WAY too strong for a lot of people. However, if you're not a stranger to over-loading yourself on caffeine (or other stimulants) and you generally like its effects, this should be a great supplement for you. Very importantly, the jitters went away by the 4th day I took it and now it's hardly noticeable. I started using it so I could easily lower my daily dose of Adderall (prescribed for ADD) and it did the job well.
