Ordered Saturday, Arrived Sunday. I had trouble getting a CAT6 cable individual ends into a normal RJ45 Plug. Possibly due to the small working area between the sheath end and the ends of the wires using the thicker 23 AWG. Thought I would try out the Pass-Thru plugs. So ordered the Klein Plugs and this Klein Crimper tool. Must mention that I am happy wiring Cat5 and Cat5e using normal plugs. My problems arose with the CAT6 cable. Perhaps, I suspect, because my CAT6 cable is 23 AWG, and by the way it also has a central Twisted Pair separator inner running through the cable. Anyway when it arrived I straight away dived into plugging my CAT6 cable. I had read the reviews regarding being unable to wire the thicker AWG cable so had that in mind when setting things up. Eventually, after about 40 minutes of faffing about trying different things and perhaps reducing the length of my cable by about a foot I plumbed for forgetting about the 1and 1/2 inch or 2 inch measurements from the end of the sheath to the wire ends and went for 4 inches approx which meant I could work on the wire ends only and not worry about the sheath end after I realised I could just pull them through when I had them in the proper order and they were passed-through the plug. The wire ends, or wire tips, have to be jammed tight close to each other, no daylight between the wires going into the plug and then slowly passed into the plug. Once you have jiggled a little bit and they look in order, with no wire having jumped on top of another, etc. Then you can push more firmly to get the wires engaged into their proper channels. Re-check again, as best you can. Then push more firmly and positively and they will go through. Then I pull on all the wires which are through and feed and work the sheath into the plug, it does go in, past the crimp position. Once through and happy they are in the correct colour order I then pull each pair, by original colour twist order, then pull on each wire individually with a small pair of pliers, just to take up any slack on the wires inside the plug between the sheath and the wire ends. Re-push sheath to ensure still fully in position. The second plug was done in about 15 minutes. I concentrated on the wire ends and working them constantly to get them very close together before even attempting to try to put them into the plug. Tip - Re-cut if the wires ends are not all in line with each other. I fully expect to get this time down the more I use these plugs. By the way once I had the actual wires through in correct order it was so easy to use and crimped perfectly and also cut the wire ends off the plug. Nice job. Will be using Pass-Thru for CAT6 and thicker cabling without a shadow of doubt. Negative is the wire stripper, waste of time. Too bulky a tool to maintain constant pressure for a sheath cut and turn the tool around the cable, tool is too bulky for that. Use a separate sheath cutter. This review is mainly about the pass-through plugs I suppose but that is where the pain is in wiring CAT6 23 AWG. You would still have that pain and more with normal plugs. But pass-through plugs helps immensely by giving you more wire to work with. The Crimp tool works fine, does the crimping part very well. Not tested on any other type of pass-through plugs. Only done 2 RJ45 plugs - but very pleased with this pass-through system (mainly because I have never, ever, managed to get my CAT6 23 AWG cable into any normal Cat 6 RJ45 plug successfully - amateur, I know)

After realizing my old crimp tool was not as good as it once was I decided to pay the extra and buy a more upmarket version. The tool is a pleasure to use, it is solid and has a good feel and action to it. so far it has not made a bad connection and crimps the connectors with ease. Although it does cost more than the cheaper versions after using it for some time, I would say the speed of use and accuracy of the tool reduces potential rework and will in the long run save time and in turn money. If you are looking for a new RJ45 tool I would strongly recommend this one.

I can confidently attest to the exceptional performance and versatility of the Klein Tools Pass-Thru Modular Wire Crimper, VDV226-110. This all-in-one tool has become an indispensable part of my toolkit, providing fast and reliable results for a wide range of tasks. One of the standout features of this crimper is its all-in-one design, which combines cutting, stripping, and crimping functions into a single tool. This streamlined approach eliminates the need to carry multiple tools or switch between different devices, saving time and effort on the job. Whether I'm cutting wires to length, stripping insulation, or crimping connectors, the VDV226-110 handles each task with precision and efficiency. The pass-thru design of the crimper is another innovative feature that sets it apart from traditional tools. Unlike conventional crimpers that require precise alignment of wires within the connector, the pass-thru design allows wires to pass completely through the connector before crimping. This ensures a secure and reliable connection every time, even with varying wire lengths or conductor sizes. The result is consistently professional-quality terminations without the need for guesswork or rework. Durability is a hallmark of Klein Tools, and the VDV226-110 is no exception. Constructed from high-quality materials, including a rugged steel frame and durable handles, it withstands the rigors of daily use in demanding work environments. The ergonomic design provides a comfortable grip, reducing hand fatigue during prolonged use and allowing for greater control and precision. The bright yellow and black color scheme of the VDV226-110 not only enhances its visibility on the job site but also reflects Klein Tools' commitment to safety and quality. The tool meets rigorous industry standards for performance and reliability, providing peace of mind for users. Overall, I highly recommend the Klein Tools Pass-Thru Modular Wire Crimper, VDV226-110, for professionals and DIY enthusiasts alike. Its combination of versatility, efficiency, durability, and safety features make it an invaluable tool for anyone working with modular wires and cables. Whether tackling residential wiring projects, network installations, or telecommunications work, this crimper delivers fast, reliable results every time.

Very good quality crimpers. No problems with all terminations made using fairly cheap connectors. The cable colours are on both sides of the tool which gives you confidence when terminating. Nice ratcheting feature gives you confidence you have crimped with enough pressure. The tool is very compact and easy to use. Not sure why it says they can not be used with non pass through connectors.

Comprei vários alicates da China e nacional mais esse devido o preço poderia vim melhor ele com 2 meses começou a criar a ferrugem nos lados e a lâmina de corte criou também de 1 a 10 eu daria um 7

Après avoir utilisé le produit similaire vendu par Amazon. (2 mille + notes / note 4.x et ayant des résultats peu fiables. De nombreuses tentatives et nécessitant de refaire les sertissages pour obtenir une connexion solide, j'ai été extrêmement satisfait de ce produit. Mécanisme à cliquet, assure une connexion solide et complète. La bande et la coupe incorporées sont très pratiques et précises. Les schémas de câblage des deux côtés de l’outil constituent une confirmation infaillible. Les connecteurs sont un peu plus chers que la marque XXX, mais valent le coût compte tenu du gain de temps et de la fiabilité. Fabriqué aux États-Unis ou en Chine... encore une fois, un prix inférieur ne signifie pas toujours un meilleur rapport qualité-prix. Je recommande fortement ce produit

I’m really impressed with this Klein pass-thru crimp tool. Before getting it, at least 1 in 3 of the cables I made would either not work at all or wouldn’t run at full speed, which was frustrating and a waste of time. Since switching to this tool, every cable I’ve made has come out clean and reliable, so it’s already saved me both time and money. I also like that it’s basically an all-in-one tool, which makes things so much easier when I’m up ladders or working in tight spots. It feels solid in the hand, the ratcheting action is smooth, and the pass-thru design makes setup straightforward. Overall, a great, dependable crimper that has made my cable jobs much more efficient.

Great quality but stripper does not fit properly

Very good the rj45 crimping is so easy with this tool but i noticed that if you dont use klein rj45 plugs there is a possibility that the cable you made will not pass the pair test. If you want to be sure for your cable use klein plugs or similar good plugs. First i used i Chinese similar cheap rj45 crimper but it has nothing to do with this tool. Klein crimpimg tool cuts the cable and presses the pins very good.
