RJ45 pass-through crimping pliers: speed and precision on site
The Melchioni MK580 is designed for installers and network technicians who want a reliable crimping tool for fast and uniform RJ45 8P terminations. The compatibility with pass-through connectors makes it perfect when time optimization is needed: the conductors pass through the plug, the wire order is immediately verified, and with a single action, the pliers crimp and cut the excess with a clean cut. Result: clean finish, correctly perforated contacts, and a tidier termination, ideal for rack cabinets, patch panels, and wall outlets.
Cat5e, Cat6, and Cat6a compatibility: UTP and FTP without complications
LMK580 is developed to work with Cat.5e UTP/FTP, Cat.6 UTP/FTP, and Cat.6a UTP/FTP connectors, covering most modern LAN installations and data systems. Whether you are wiring an advanced home network, an office, or a more structured infrastructure, the extended compatibility allows you to use a single tool for multiple standards and shielding types.
Advanced ratchet: consistent crimping with less effort
The ratchet ensures controlled and repeatable pressure: the crimping is completed correctly before release, reducing errors and rework. This results in more reliable connections and less manual fatigue in repetitive tasks. The quick release helps maintain a smooth work rhythm even during intense cabling sessions.
Ergonomics and safety: firm grip and responsible use
The two-tone handles with rubber inserts improve comfort and control, even with sweaty hands or light gloves. Like any tool with moving and cutting parts, it should be used with care: check the integrity of the pliers before use, avoid contact with fingers or body during cutting, and use it exclusively for its intended purpose, without modifications.
