The Tolsen 38058 ratchet crimping pliers are designed to secure ferrules on electrical wires with precision. These tools handle a wide range of wire gauges from 0.25 to 10 mm² (AWG23-7), making them versatile for both professional electrical installations and home repairs. To ensure a consistent connection, the tool features a self-adjustable ratchet mechanism equipped with a star wheel for fine pressure control, which prevents the over-crimping of ferrules. For ease of use, a quick-release trigger is integrated inside the handle, while a safety lock keeps the pliers securely closed during storage. The 175 mm long tool is finished with ergonomic ABS handles that reduce hand fatigue during repetitive tasks.
