RJ45 Crimping Tool Ethernet Crimp Tool Crimper for RJ11/RJ12 Standard, RJ45 Pass Through Connectors, Yellow

As a tech enthusiast diving into network setups, the RJ45 Crimping Tool for RJ11/RJ12 and RJ45 Pass Through Connectors has been a fantastic addition to my toolkit, earning a strong 4.5 stars. This yellow crimper feels sturdy and well-built, with a comfortable grip that makes repetitive tasks a breeze. It handles RJ45 pass-through connectors and RJ11/RJ12 standards flawlessly, delivering clean, reliable crimps every time. The built-in cutter and stripper are precise, saving me from juggling extra tools, and the compact design is perfect for tossing in a bag for on-site jobs.My only gripe is the lock mechanism—it tends to engage unexpectedly mid-use, which is a bit annoying and slows down the workflow. It’s not a dealbreaker, but it disrupts the otherwise seamless experience. Aside from that, this crimper is a high-quality, versatile tool that’s ideal for DIYers or pros setting up Ethernet or phone lines. For the price, it’s a great value, and I’d recommend it to anyone needing a reliable crimping tool, lock quirk notwithstanding!

Just used this over the weekend. I will never use another old style tool. This uses the wire pass through connectors. Once the wire is in place the tool will crimp put the spikes in and cut the excess wire. Amazingly easy.Tip: you'll need to get the connectors that allow the cable to pass through the end.In the past I have made multiple connections with a 50/50 rate of an issue. This was much easier and 100% of them worked. Plusses are the diagrams on the tool itself which makes it easy to get the color order right.What does the tool do? it cuts, splices the cable, and crimps perfectly while cutting the excess off. Would recommend as I pushed very hard and it felt like a solid tool. Highly recommend.

Great replacement for my Klien that got stolen. Works well and I love the locking feature and the cable sleeve stripping notch.It doesn't always cut off all the excess wire when crimping, and needs a bit of wiggling to remove the remaining strands. Overall good crimper though, it does the job well.

I bought these to see if they did as well as name-brand crimpers I used to have. They are about 95% as nice as my name brand crimpers, for less than half of the price. I have no desire to replace this crimper with the name brand, to be honest.While I haven't found a 'perfect' crimper yet, these work very well. I have had ZERO failed crimps with this tool--The depth of the crimp is appropriate. It doesn't seem to over crimp, nor under crimp. The blade cuts reliably. I will say that stripping with these isn't great--They cut a little deeper than I like, just like the name-brand crimpers did. My favorite stripper tool is still the little one-piece plastic thingy that comes for free with all kinds of stuff.I have used this crimper with both 'name brand' RJ45 plugs from the big box store as well as 'no name' plugs from Amazon. I can't tell the difference.All in all, if you're on the fence as to these vs name-brand, pick these up. They're probably off of the same production line, anyway.

Easy to use and easily worked on my first try.

Definitely a solid crimp tool and cuts everything decent except for pass through heads. Deal breaker based off what I needed it for.

I tried this crimper on some RJ45 connectors, and it worked great. I appreciated the extra cable cutting blades included in the purchase. The durability and build quality are top notch.

Heavy duty, small and locks closed. Better than expected for the price.
