G'day! If you've ever tried to make your own Ethernet cable (a patch lead), you know the absolute frustration. You're there, squinting at those eight tiny, bloody wires, trying to get them in the right T-568B order (White-Orange, Orange, White-Green...). You spend ages getting them flat and straight. You trim them perfectly to length, shove them into that little clear RJ45 plug, and... bugger.

You've got two wires that have crossed over, or one's not pushed in far enough. It's a proper dog's breakfast, and you've just wasted a plug. It's a fiddly, annoying job that's the bane of many a DIYer and even some pros.

But there's a fair dinkum brilliant solution that makes this job 100 times easier. It's the RJ45 pass through connector.

So, What is a Pass Through Connector, Exactly?

A RJ45 pass through connector (sometimes called an "EZ-RJ45") looks almost identical to a standard RJ45 plug. But it has one magic difference: the little tunnels for the wires are open at the end.

Instead of having to trim your 8 wires to the perfect length and jam them into a closed-off plug, you just:

1. Strip the cable.
2. Get your 8 wires in the right order.
3. Shove them all the way through the plug, so they poke right out the front end.

This is a total game-changer, mate.

The Ripper Benefits: Why It's a Schmick Idea

So why is this simple change so bloody good?

• You Can't Muck Up the Order: This is the big one. Because the coloured wires are sticking right out the front, you can visually check that they are in the 100% correct order before you crimp it. No more guesswork.
• Way Less Fiddling: You don't have to be a surgeon trying to trim all 8 wires to the exact same length. Just get them in order and push them through. It saves a heap of time and frustration.
• A Better, More Reliable Connection: Because you can pull the wires all the way through, you can make sure the outer jacket of the cable is properly seated inside the plug for a good, strong strain relief. It also allows the twist in the wire pairs to be maintained closer to the pins, which is better for signal quality and reducing interference.

The One BIG Catch: You Need the Right Tool!

Righto, listen up, because this is the non-negotiable part. You cannot use your old, standard RJ45 crimping tool. It won't work.

You must use a specific RJ45 pass through crimping tool.

This tool is a clever bit of kit. It has the standard crimper to push the pins in, but it also has a built-in blade at the front. As you squeeze the handle, it does two jobs in one: it crimps the pins and it neatly slices off all the excess wires that are poking out the front, all in one go. It's a beautiful thing.

The CRITICAL Safety & Compliance Warning: DIY vs. Pro

This is where we get dead serious, mate.

• DIY: Are you making a "patch lead" (a loose cable to run from your wall socket to your computer or from your modem to your router)? Go for your life. This is a top-notch DIY job, and a RJ45 pass through connector will make it dead easy.
• PRO ONLY: Are you wanting to install a new data point? This means running a data cable inside your walls, floor, or ceiling and terminating it at a wall plate.

In Australia, this is strictly not a DIY job. Any fixed data, communications, or telephone cabling must be installed by a licensed cabler (registered with ACMA).

Why? It's the law. A dodgy data install (especially with cheap parts from a non-specialist supplier) can create interference (messing up your and your neighbour's NBN). Worse, if it's run too close to 240V power wiring without proper separation, it can become a serious electrical hazard.

A Professional Job Needs Professional Gear

A licensed cabler or licensed electrician knows that a rock-solid, high-speed network relies on high-quality, compliant components from end to end. They get their gear from a trusted electrical wholesaler to ensure it's all trade-quality.

As one of Australia's most comprehensive electrical wholesaler and supplier networks, Schnap Electric Products stocks the lot for the professional installer. They've got a massive range of high-quality, professional-grade data gear, including RJ45 pass through connectors (Cat6 and Cat6a), the matching pass-through crimping tools, high-speed data cable, and all the wall jacks and plates that a qualified professional needs to do the job right. For a connection that's fast and reliable, the pros start with quality gear from a supplier like Schnap Electric.
