RJ45 Pass-Through Connector Crimper (RJ CRIMP T304)

RJ45 Pass-Through Connector Crimper

The RJ45 Pass-Through Connector Crimper, article number RJ CRIMP T304, is a crimping tool designed for fitting RJ45 pass-through connectors to network cable. It belongs to the Tools & Hardware range and sits in the Tools & Testers category.

Crimping is the step where a plug is pressed onto the ends of a cable so that the wires make firm contact with the connector contacts. A good crimper keeps that job quick and repeatable, which matters when you are terminating several cables on a site or in a comms cabinet.

Pass-through connectors are RJ45 plugs with an open end, so the cable runs straight through the plug before it is crimped. This lets the wires be trimmed and seated neatly before the connector is pressed, and it suits installers who want a tidy finish on each cable end.

This tool is aimed at installers, electricians and IT staff who fit network cabling for offices, homes and small commercial sites. Keep it with your other cable tools so it is ready for the next job.

RJ45 Pass-Through Connector Crimper (RJ CRIMP T304)

The RJ45 Pass-Through Connector Crimper, article number RJ CRIMP T304, is a hand tool for terminating network cables with RJ45 pass-through connectors. It is listed under Tools & Hardware and Tools & Testers, which makes it a fit for anyone building or maintaining a cabled network.

What it is for

RJ45 connectors are the standard plugs used at the ends of Ethernet cables. A pass-through connector has an open back, so the cable passes fully through the plug before crimping. Once the wires are arranged and trimmed, the crimper presses the plug onto the cable to lock the conductors and the outer sheath in place.

Key features

  • Designed specifically for RJ45 pass-through connectors
  • Hand-operated crimping action for terminating Ethernet cable ends
  • Supplied as a Tools & Hardware item in the Tools & Testers category
  • Suitable for installers who work with network cable on a regular basis

Typical uses

The crimper is used when you need to make custom network patch leads, repair a damaged cable end, or terminate new runs in an office, home or light commercial installation. Installers may also use it on site where pre-made leads are not practical.

Using it well

Strip the cable jacket to the length recommended for your connector, arrange the wires in the correct pin order, trim them square, and then insert the cable fully into the pass-through plug before crimping. Check that every wire reaches the front of the connector and that the jacket is gripped by the plug. Test the finished lead with a cable tester before putting it into service.

Who should use it

This tool suits electricians, network installers, IT technicians and keen DIY users who terminate their own cabling. It is a practical addition to a toolkit for any job that involves Ethernet cable.

Care tips

Keep the jaws clean and free of debris, store the tool in a dry place, and inspect it regularly for wear. A worn crimper may give unreliable connections, so replace it when it no longer grips and presses cleanly.
