Klein Tools 80024 Ratcheting Data Cable and RJ45 Crimp Tool with CAT6 Plug 50-Pack, Pass Thru Installation Tool Kit

This Klein tool is the best I have used for attaching RJ45 connectors. Easy to use and the included Klein ends work perfectly.

I saw a video somewhere about using this passthrough crimper for Cat6 cabling. I'm still using up my old Cat5 cable, but I know from sad experience it's hard getting the conductors in order, leading to unusable crimps and wasted connectors. This Klein crimper paired with the Klein brand passthrough connectors made the crimps 100% successful! Yes if you follow the directions, it wastes a couple of inches of cable because you leave the conductors long enough to straighten, reorder, and push, then pull them through the connector. But the best part is you can inspect the conductor order easily BEFORE committing to the crimp, without having to peer through the plastic. With the color charts right on the crimper, there's no excuse for checking it one more time, and restarting if it's wrong. I feel like I could gain some speed with practice. I'm definitely not a high volume crimper. You could argue it's not worth the expense owning such a nice tool, but I figure I saved a lot of money pulling and terminating the wires myself, so the success is a nice reward. I like that you don't have to carry around any additional tools... the stripper is a little loose for Cat5e but I imagine it's perfect for Cat6. I was able to cut the cable, nick the outer jacket adequately, and even drag the "string" along the Klein handle to cut the string off well enough I didn't need scissors. And I was able to cut the conductors flush after reordering in the case that they weren't already straight. I can't find my Ethernet cable tester so I decided to wing it. So far the equipment all shows a solid connection. Good enough! Now I need to finish the job.

Works great. I bought a cheap chines crimper first and many of my bables failed the test. I re-crimped thise same connectors with this and it works. I will get Klein electrical tools whenever possible. They are always pro quality, but often priced reasonable enough that they make sense for a DIYer.

I might still be making up cables for a living if I had found this earlier. I'm 65, with some old gnarly fingers that don't like to do precise work anymore. I've made up about a million (my hands thinks so anyway) rj45 T568B connections. My old crimpers required stripping the outer jacket back, untwisting the wires, then holding them together in a very specific color pattern, trimming them square at just the right length, sliding the 45 connector on and then crimping. If a wire didn't align just right and "jumped" a slot...you cut it off and started over. This crimper starts out the same, strip the jacket, untwist the wires, but then... it's different. You fit each wire in THROUGH the pass through RJ45 connector. This gives you the chance to check the color code mapping BEFORE you crimp and waste a connector. Once your sure the wires are "slotted" correctly, just give them a good tug to make sure they're seated , slide the connector in the tool and squeeze. It trims the wires off flush with the end of the connector, and presses the strain relief into place. The crimps are dead on accurate and the ratcheting mechanism gives you much needed leverage making for easier crimps with less fatigue over traditional crimpers. Awesome value, and a quality tool. Plus, it's more compact and fits in my tool bag easier.

Works great with good crimps and clean cuts. There are so many subtle things about pass through connectors many people don’t know about. Using Kline crimpers with Kline pass through connectors gives you a quality connection without thinking about it.

At $50, this is an expensive tool to me. It is roughly twice the price of no-name alternatives. It's not like I'm making 100's of cables with it. I will probably make a dozen, but they will be of custom lengths for direct burial CAT6, PoE access points, as well as PoE cameras. At that rate, it adds about $4 to each cable I make with it vs $2. However, my time is also expensive to me too. With the right tool, the job of attaching connectors to the cable can go faster. I have used a non-pass through RJ45 tool to crimp cables in the past. Closed-end RJ45 crimping has several concurrent and frustrating challenges that must be balanced while crimping: 1. Getting the wire ordered properly and keeping it that way while also.... 2. cutting the wires to a flat end to go into the connector... 3. with the wires not too long so that the outer sheath won't get crimped to the connector... 4. nor too short that it won't reach the blade conductors at the end of the connector either... 5. without letting go of the 8 wires pinched flat to go into the connector... 6. otherwise the wires get out of order and/or their lengths are no longer even and fit correctly into the connector. Mess up any of the above, and one wastes the time taken and often a connector and some wire. Trying to identify which end is bad isn't easy. Sometimes one must guess and then one has a 50/50 chance of doing 2 ends again instead of just 1. One must have a first attempt success rate in attaching connectors correctly better than 1/2 the time or one won't be able to complete a cabling job. At best, that is a frustrating art for me. My wife has helped when I've run cable for church and she is more patient and nimble crimping closed end RJ45. However, it is a challenge for her as well. At times, we found ourselves hitting that 1/2 time success rate. Trying to get a cable done could seem to take forever. At that rate, $2 or $4 per cable seems worth it. I'm installing CAT 6 at home and knew that I should get a different tool to deal with crimping the thicker cables. I found the pass through connectors and crimping tools and realized it should make the task easier as points 2,3, and 4 are no longer concerns. The crimping time is cut so that point 5 is no longer as critical. The 6th point also is less critical because if the wires are out of order then it will be evident before crimping. Pull the wires out of the crimping tool and try again. I tried a no-name version of the same type of pass-through RJ45 crimping tool first. It was about 1/2 the price of this one. After being very disappointed with the performance, I figured I would spend the extra money to buy this name brand version of the same tool. This tool performed much better and is adequate to do the job. The one disappointment with this tool was it could not strip CAT 5e with the built in stripper. This was a problem with the other pass through tool I purchased before buying this one. I used a small plastic tool with a blade from my non-pass through kit to strip instead. I suspect the built in stripper will work for CAT 6 or 7 as those cables tend to be thicker, but have not tried it yet. Critical improvements in this tool vs the other pass through crimping tool: 1. The Klein tool cuts the pass through wires off at the end of the connector when crimping. The other tried, but couldn't. There was 1 wire in my test with the Klein tool that need a little tug to separate the waste wire insulation from what was in the connector after crimping, but that was all. The other tool required using a box knife as the blade on it did not make sufficient cuts to removed the excess with modest pulls. Not needing a cutting surface for the excess is not an absolute requirement, but it is important since the cable install location may not have such a surface. 2. The RJ45 connector can be easily removed after crimping. A small pull was all it needed. The other tool would not release the connector after crimping. I had to use a jeweler's flat head screw driver to depress the tab on the connector inside the crimping tool's receptacle so I could remove it. Note that the Klein tool held the RJ45 connector latched in too--if it weren't crimped. That's a feature and not a bug. It helps free a hand from holding the connector in place before crimping. Pulling it out before crimping isn't a normal thing to do so it isn't a problem. Being able to remove the connector easily is not an absolute requirement, but a cable install location may not be well lit to see the tab to pry. The length available at a PoE camera drop or WIFI access point may not be convenient to be messing around with a small screw driver over one's head as one tries to poke and prod a connector out of the crimping tool that is being held with the other hand. If one is going to be making a dozen custom cables or more, I recommend buying this product. For the pro and the amateur, it will likely be worth the efficiency gained compared to the alternatives.

I have a ton of Klein tools (the big back pack, wire strippers, screw drivers, etc.) so my expectations were high, but I was also confident in purchasing this tool. Like any other Klein tool, the build quality is solid. It does everything from cutting, stripping, to the final crimp. You can pass through the wires as long as you need, pull it nice and snug, and it'll trim the wires down to the edge perfectly. The blades are very sharp and built to last. Did some practice crimps (in the photos) then proceeded to wire up my building with CAT 6 POE cables for my UniFi system (dream wall, APs, cameras, intercoms, the whole nine). Saved so much time and effort. Every single crimp came out perfectly and the connection was solid. Highly recommend. Will never do non-pass through crimps again!

Making cat5e Ethernet cables is an absolute joy with this tool! My daughter insisted on using a wired connection from her gaming desktop to our router located two rooms away down a long hallway. I purchased 200 feet reel of cat5 cabling and tried using the harder method of stripping the end of the cables and needling each one of those very thin wires through the teeny holes in the plastic data plug connectors. It drove me absolutely insane causing me to rage quit the project. After some googling I discovered this Klein pass through stripper and crimper and I nearly cried. Without hesitation I ordered it from Amazon. The tool is extremely easy to use and is self contained with a cutter to trim your cable and a stripper to remove the rubber outer jacket with precision and ease. The tool itself has a color coded guide that tells you the order in which the tiny wires fit through the plastic connectors. Once you have them straightened out and in the proper order, they slide effortlessly into the connector and the Klein tool will crimp the connectors onto the end of the wires. Works PERFECTLY. I enjoyed it so much that I asked everyone in the family and some friend if they needed Ethernet cables. You can make your cables as long as you want them which is awesome when you're trying to minimize wires for a clean look behind your devices. I can't say enough about this tool. Get it. You won't regret it!!!

Excelente produto

This gives users the ease to repair or terminate cables at desired length, great product

1000/10 Me gustaron mucho, he usado muchas marcas chinas y otras profesionales y siempre tengo problemas con este tipo de cable CAT6 reforzado para exteriores, el cobre es mucho más duro y eso hace que a veces los ponchados no sean 100% exactos, en este caso pasó igual, pero como se aprecia en el video basta con darle uno giros y se caen por sí solos. La gran diferencia es que no tengo que hacer una fuerza grande para ponchar, el agarre se podría dificultar con una mano pero no necesitas gastarte el antebrazo como en otras marcas. De momento las he usado con CAT6 reforzado, el CAT5e y el CAT6 para interiores debe de hacer un corte limpio SIN PROBLEMA. Actualizaré en caso de devolución o problema, muy contento con la compra. El único problema que le veo es que no tiene seguro y tienen que estar siempre abiertas, no como otras ponchadoras de ese tipo, ese detalle es molesto en cierta medida pero te acostumbras.

My first outing to make my own Ethernet cables and this tool worked very well. Although they only mention cat 6 in descriptions it was fine making up my cat 7 connectors. Great bit of kit.

I'm a fan of Klein tools, and this tool is great, but unfortunately, the first one I was sent had bent pins inside, so it ruined every connector I tried to crimp. A trip to the post office to return it and another order got me a new unit that worked perfectly. I've crimped a ton of RJ45 (technically, 8P8C modular) connectors the old way, where you have to cut all the wires to the perfect length meticulously, and half the time they didn't quite go into the connector all the way. With this tool (and the appropriate pass-through jacks), you'll never have to worry about that again. It's far easier to cut the wires and pass them through; then, the tool cuts off any excess for a perfect, clean-looking connection every time with the perfect amount of jacket inside the connector. This tool has also never messed up the locking tab on connectors, as my old tool often did, which meant the connectors wouldn't "click" into the jacks securely without bending it back first. This tool has very handy wiring diagrams on the back and front, which is a godsend. I don't technically *need* this, given how many connectors I've made, but it's always handy to have a reference to check before you crimp down to ensure no mistakes were made. (I've still screwed up a few, but that's not the tool's fault!) I like that this tool has a much more compact form factor than my old Ideal brand crimper, and it takes way less force. Someone without especially strong hands could easily use this tool, and my non-techie wife has helped me do several and hasn't had any issues. The cutter works great both for cutting through Cat6 cables and trimming the bent ends of wires off after sorting and straightening them. There's also a groove that can be used to strip the jacket, which works fine in a pinch, but you have to be careful not to cut too deep and cut the wires. It's never going to work as well as a proper radial stripper like the Klein VDV110-261. This crimper should also work with non-pass-through connectors, although the blade could shave the end of the connector off on some, so you might want to test a crimp before buying hundreds of third-party connectors to use with this tool. Hopefully, I was just especially unlucky to get a defective unit on my first order, but make sure you test the tool before taking it on a job! Bonus: Here's the procedure I use to crimp cables with this tool and pass-through jacks: 1. Using side cutters or the built-in cutter, trim your cable to a couple of inches longer than you need. 2. Use a dedicated rotary wire stripper (or, if you don't have one, carefully use the built-in groove with the cutting blade) to make an incision around the cable's jacket. Grab the end of the cable after the cut and twist, bend, and pull the jacket off, which should be removed cleanly with about an inch and a half of the wires exposed. 3. Using small scissors or a side cutter, splay the wires and clip the pull string and the plastic cross separator off as much as possible. 4. Now untwist the wires almost to where the jacket is, and arrange them in a fan-shape as per the diagram on the front of the tool, starting with solid brown. T-568B is the most common arrangement, although you can use T-568A if you prefer, or it is used in your particular environment. Just be sure to use the same on each end of the cable (unless you intend to make a crossover cable). 5. With the wires in the correct order, grab them firmly with your thumb and forefinger, working them side to side as you pull them out, which will help straighten the wires. 6. The very ends of the wires will be much more difficult to straighten and likely won't pass easily through the connector, so trim off about 1/2 an inch of the wire using the built-in cutter or side-cutters. 7. Check that the wires are still in the correct arrangement. With the retention clip facing you and the brown wire on the left, insert them into the 8P8C jack, angling slightly towards the clip side of the jack. You should be able to wiggle them around a bit until you're able to slide them through the connector. If it's not happening, the wires might need additional straightening or trimming. If one or two of the wires aren't going through enough, they might be getting stuck inside the connector and bent, which is not good, or they might need to be untwisted a little more. 8. With the wires out, push the jacket as far into the connector as it will go and pull on the wires to ensure they aren't bunched up in the jack and are as far out as they will go. 9. Now, bend the wires so that they are coming straight out of the connector (so they don't catch the blade on the crimper), and slide the connector firmly all the way into the crimp tool with the clip facing up, matching the jack on the tool. 10. Squeeze the crimper firmly until it releases, then pull the connector out. Check that all wires were cleanly cut flush with the connector end. If not, this could potentially cause a short. If the connector wasn't inserted fully or you didn't squeeze it completely, the cut may not be perfect. In these cases, you can usually just crimp again to fix it. You'll now have a perfect connector and a mess of tiny wires and debris to clean up!
