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

This tool has solved a lot of my connector problems. I may have had a bad batch of connectors before, but with this tool and the pass through connectors I’ve had no problems. I used to use these at work and very happy they’re now available on the consumer market. Highly recommend this tool.

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.

OK, and get the job done. The alignment of the blade is not perfect, and at times, have to work to get the cut wires off. Not as good as my Kline, but cheaper. I think it's a good value.

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.

definitely worth the money, the crimper works well and the quality is good I had to adjust the blade in order to use non-pass through connectors

Two major design flaws make this crimper very annoying. In the space where you chop/trim cables, the razor blade does not extend all the way to the back of the throat. So, when you put strands of cable in the throat for a trim, it does not touch the first one or two strands. Then the lock button is in a spot where it unintentionally locks, and it is always at the most inopportune time. This crimper would be fine for an occasional crimp, but if you are looking for a tool that you will need to use all the time, this is not for you.

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!

Works like it should.

Takes a bit of practice, but I now pretty good at installing RJ-45 connectors. Installed about 20 now for my basement reno. Good construction and looks like it will last a long time

Bad quality, mostly items are used.

Wow, I was not expecting such good quality for such a good price. As a general guide I do around 50 connections per day with zero failures. I immediately ordered 2 more as spares
