I couldn't figure it out by myself. Thanks for the great tutorial, took some fiddling but I got a working cable in 15 minutes.

Rather than hand untwist the 4 pairs, take a small screwdriver and slip it between each pair near the jacket and slide it toward the cut end. This will put enough tension on the wires to straighten them out as they unwind. You might need to leave a bit of extra wire length to get them to unwind far enough and cut the excess off with wire scissors before inserting the wires into the plug. Try it a few times and you'll quickly figure out what I am talking about and how much wire to leave exposed.

I just bought a similar kit, probably from the same maker with a different color tool and slightly different accessories. The whole package was cheaper than the Klein regular cable crimper I already had. I bought 100 male ends cheap on prime day not thinking that they were feed through. Decided to buy the kit with the feed through crimper and it already has everything I needed for 20 bucks. I was able to repair some network DVR cables the rats had chewed up with a few couplers so I didn't have to rerun new cables under the house. I later discovered I was crimping the wires reversed but as long as both ends are the same it doesn't care. I had to cut and redo one because it needed it to match all the way to the DVR and then it was happy again and nothing smoked. Never done this before so been a learning experience but I think I have it all figured out now. Another thing I found was using a load bar that you preload the wires into then slide into the plug and crimp, but I think you need special plugs for them or buy them as a package with the plugs. No matter it seems to be the same quality as the Klein tool is and you get everything you need to start making or repairing cables for a much better price.

Thank you for this!

So this crimper is only for connectors with the built-in strain latch. You can't remove the strain latch crimper plate to be able to crimp the connectors without it.

Can the blades be replaced?

Do I need to buy pass through crimper or I can use the regular crimp tool. Want to know if I can use the pass through rj45 connector with standard crimp tool and then cut excess wires with scissors? Thanks

What brand sir?
