PETECHTOOL RJ45 Crimp Tool Ethernet Pass Thru Crimper with 5Pack 8Pin Replacement Blades for Pass Through Cat5 Cat5e Cat6 RJ45 RJ12 Regular and End Pass Through connectors

It took a bit to get used to it after years of using a regular crimping tool but it works well. When you line them up to push them through it feels like it's not going to go then all of a sudden slides right in. I usually push them up until the cable jacket is under the crimp connector. For outdoor use you would definitely need some heat shrink tubing or an IP65 dust cover around the opening. Nice that it comes with a few extra blades but it would've been great if there was a place on the tool to store them instead of just a baggie in the connector jar.

I did not want to buy these at first for the fact I have never used pass through connectors before. So I bought these since they were good priced. After getting them and falling in love with pass through connectors I fell in love with this tool. It is very well made and works very well. I like how it has the a and b order of the wire pattern on then.

First package came empty. Contacted Amazon, sent out a replacement right away. I did have to suffer through a few errors in telling me that I had to send back the first set of tools, but that was taken care of with a phone call. The crimpers work great. Only flaw is that the cutter seems to wear out quickly, especially at the end. Seems like pin 8 or 1 is always left uncut. Good news is that the tool comes with an extra set of cutter blades.

This crimping tool is made in the same factory in China and slapped with various dealer-seller brands. I bought this not for the tool but for the five (5) pack replacement blades included with the tool. I purchased a similar-looking, including the colors, crimping tool (for regular and pass-through RJ-45 connectors) for a home networking project four (4) years ago, and the blade for the RJ-45 slot dulled over time, and no replacement blades were included. I was only looking for replacement blades when I chanced upon this PETECHTOOL that comes with a five (5) pack blades for the RJ-45 slot. PETECHTOOL also sells only the five (5) replacement blades for more than half the price of the tool with the included blades -- which is this set. Hence, it's a no-brainer to get the tool with the bundled replacement blades rather than just the blades. Of course, the replacement blades bundled with this PETECHTOOL crimper fit my other, older but similar-looking crimper. (see side-by-side photo). The tool itself (like the old one, which was sold as "SOLSOP") is well-made, and the best part is the ease of blade replacement - it only takes the correct size of Phillips screwdriver. Now I have a spare crimper for my casual networking needs, or I could give this new one as a gift.

This crimping tool will give you problems. Does not crimp down #4 and sometimes 4 & 5. I recommend getting a good rj45 crimp tool

I use this daily and it preforms flawlessly.

I almost didn't get this tool, because I wanted one that had the 568a and 568b wiring orders on the side, but was pleasantly surprised to find this tool does have it stamped on the side. The tool is high quality and works well. Fit my needs perfectly.

Pass through RJ45 connectors are a huge timesaver. Being able to verify wiring before crimping eliminates crossed wires. This tool makes it vastly easier to get it right.
