Solsop Crimper Kit 16 Pass-Through RJ45 Crimp Tool Kit for Cat5–Cat6

For anyone assembling or repairing Ethernet cables for voice and data applications, the Solsop Crimper Kit 16 combines pass-through RJ45 crimping with cable testing in one compact kit. Its tool crimps and trims pass-through connectors on paired-conductor round STP/UTP cables, while the wiring diagram on the tool helps you check wire order before crimping.

The kit also includes a cable tester and cable-prep tools, so you can make and check a cable as part of the same task.

Key points

Pass-through connectors let the wire cores extend through the plug, making their order visible before crimping. The Solsop tool crimps the connector and trims the protruding wire ends, bringing those steps together for Cat5, Cat5e, and Cat6 cable work. This design is intended for pass-through RJ45 connectors rather than standard, non-pass-through plugs.

The kit includes 50 RJ45 pass-through connector plugs, 50 covers, a network/phone cable tester, pliers, and a mini cable stripper. The tester accepts cables with RJ45, RJ11, or RJ12 connectors and can help check a finished cable. It requires a 9V battery, which is not included. For someone who would otherwise assemble a separate set of crimping and testing tools, having these tools together supports a more direct cable-making workflow.

Customers often praise the tool’s ease of use and the included tester and accessories. Feedback on cutting performance and durability is mixed, and some customers report connectors jamming in the crimper. The tool’s wiring diagram and the ability to inspect wire order before crimping offer practical guidance during assembly.

Usage tips

Start by arranging the conductors in the required order and checking them against the wiring diagram on the tool. Feed them through a pass-through RJ45 plug so the wire sequence is visible, then use the crimper to secure the plug and trim the excess. This approach is useful when making Ethernet patch cables or replacing a damaged connector, because the conductor placement can be seen before the crimp is made.

After crimping, connect the cable to the included tester to check it. The crimper is designed for pass-through RJ45 plugs, standard RJ45 connectors do not have wires extending through the front for this trimming process. Replacement blades are available for the mini cable stripper.

Practical tips

Match the connector style to the tool before starting: this is a pass-through crimper, not a general-purpose tool for standard RJ45 plugs. It works with paired-conductor round STP/UTP cables and is identified for Cat5, Cat5e, and Cat6 cable work. Keep the conductors in order as they pass through the plug, then inspect the trimmed ends after crimping. A cable tester provides a separate check of the finished cable, rather than relying on appearance alone.

What to clarify

Which connectors does the crimper use? It is made for pass-through RJ45 connectors, where the conductors extend through the plug before being trimmed and crimped. It is not designed for standard, non-pass-through RJ45 connectors.

Which cable types can I use it with? The crimper is specified for paired-conductor round STP/UTP cables and Cat5, Cat5e, and Cat6 applications.

What can the included tester check? It supports cables fitted with RJ45, RJ11, or RJ12 connectors. A 9V battery is needed to operate it and is not included.

Is it worth it?

This kit makes sense for cable installation and repair tasks that call for pass-through RJ45 plugs, with the added convenience of a tester and basic cable-prep tools in the same set. The visible conductor layout, on-tool wiring diagram, and tester each support a practical step in making and checking a cable. If your work uses pass-through connectors across Cat5, Cat5e, or Cat6 cabling, the Solsop Crimper Kit 16 brings the core crimping and checking tools together for that job.
