Proster PST322 RJ45 Pass-Through Crimping Tool Kit with Rechargeable Tester

The CAT7-format Proster PST322 combines an RJ45 pass-through crimping tool with a rechargeable cable tester for Ethernet cabling work.

Its pass-through design trims excess wire during crimping, so you can prepare and finish a connector in one workflow rather than trimming each conductor separately.

For home networking, enterprise systems or troubleshooting, the kit brings cable preparation and connection checks together, with CAT6 and shielded CAT7 connectors included.

Getting the most from it

Use the tool to strip, cut and crimp Ethernet cable, then check the finished connection with the rechargeable tester. The pass-through design cuts excess cable during the crimping action, making it useful when assembling several leads or preparing a replacement cable at a network point.

The tool supports 8P8C RJ45 connectors for Cat5e, Cat6 UTP and Cat7 STP cabling. Hand-tightened screws let you adjust the crimping mode, while the 6P and 8P wiring sequence diagrams help organise connections. For a practical setup, prepare the cable, arrange the conductors using the relevant sequence guide, crimp the connector and use the tester to verify continuity and identify faults. Its stated PoE protection is designed to help prevent damage when checking cables used with Power over Ethernet.

If you are choosing between a basic crimper for occasional terminations and a combined tool-and-tester kit, this set brings both tasks into the same case. That makes it a useful format for a home network installation or a project where you want to check each lead after fitting it.

Strengths

The main advantage is the joined-up workflow: strip, cut and crimp with the hand tool, then check the connection with the rechargeable tester. The pass-through action trims surplus cable during crimping, and the textured, ergonomic grip is designed to support a secure hold during repeated cable work. A lock button helps keep the tool closed for storage, and the spare blade set provides a replacement cutting component.

The included connectors give you materials to start a job straight away: gold-plated CAT6 connectors with blue sleeves and shielded CAT7 connectors with sleeves. Buyers’ views on ease of use and durability are mixed, some find the process more straightforward than traditional methods, while others mention difficulty inserting wires or concerns about the cutting blade. Taking care to arrange the conductors before crimping can help keep the working sequence organised.

When it makes sense

It suits you if you make or repair Ethernet leads and want a single kit for termination and testing. For example, when setting up a home network, you can prepare a cable to the required length, crimp an RJ45 connector and check continuity before routing the lead. The tester is also useful when troubleshooting an existing connection, while the Cat6 and shielded Cat7 connectors support different cabling jobs within the stated range. For network projects that involve repeated terminations, the combined format helps keep the crimper, tester and accessories together.
