Crimping tool for pass-through RJ45 connectors MONTIS MT178

The MONTIS MT178 crimping tool for pass-through RJ45 connectors is a handheld tool engineered for terminating Ethernet cables with through-wire modular plugs. Designed to work with pass-through (through-wire) RJ45 connectors, this tool secures contacts and trims excess conductor ends to produce consistent, reliable cable assemblies. The tool's compact form factor and manual operation make it suitable for field work, repairs and controlled installation tasks where precision and repeatability are required.

Advantages

The crimping tool provides a stable, single-action crimping motion that ensures even pressure across all contacts for secure terminations. Its pass-through feature allows excess conductor length to be trimmed during the crimping process, reducing preparation steps and saving time on site. The tool is built with materials intended for repeated use and features ergonomic handles to reduce hand fatigue during repetitive operations.

Suitable for

• Terminating Cat5e, Cat6 and other Ethernet cables with pass-through RJ45 plugs
• On-site network installation and cable repair
• Telecommunications and data center patch cable assembly
• Field technicians and installers performing small to medium volume crimping tasks

Key specifications

• Type: Handheld crimping tool for pass-through RJ45 modular plugs
• Compatibility: Standard 8P8C (RJ45) pass-through connectors
• Operation: Manual single-action crimp with built-in conductor trimming
• Construction: Metal crimping head with molded ergonomic handles
• Use case: Designed for field and workshop cable termination

How to use

Strip the cable jacket to expose individual conductors and arrange pairs to the desired wiring standard. Insert the conductors fully through the pass-through RJ45 plug so that they extend beyond the plug end, then insert the plug into the crimping slot of the MT178. Squeeze the handles firmly and evenly until the crimping cycle completes and excess conductor ends are trimmed. Inspect the termination visually to confirm correct seating and contact engagement before using the cable in a network environment.

Usage recommendations

For consistent results, use pass-through RJ45 connectors of matching quality and ensure conductors are straightened and fully seated prior to crimping. Periodically check the crimping head for wear and keep the tool clean from debris. Use the tool within its intended purpose—hand crimping of pass-through RJ45 plugs—to maintain performance and safety.
