• Modular Pliers / Cable Crimper: The core tool used to clamp RJ45 and RJ11 connectors securely onto the ends of stripped cables. Many feature an integrated ratchet mechanism to reduce hand strain.
• Network Cable Tester: A two-piece battery-powered (usually 9V) diagnostic device. You plug both ends of a cable into it to check for continuity, open circuits, short circuits, or miswiring via automated LED scanning.
• Wire Stripper / Cutter: A handheld tool designed to slice cleanly through the outer plastic jacket of STP/UTP data cables without damaging the delicate copper conductor cores inside.
