About This

21 SIZES WITH 4 PRECISION LENGTHS: This comprehensive kit features 21 most-used ferrule sizes with unique conductor lengths of 8mm, 9mm, 10mm, and 12mm. It perfectly matches various wire gauges and ensures a deeper, more secure seated connection in terminal blocks where standard 8mm ferrules might fall short.
99.9% PURE OXYGEN-FREE COPPER: Crafted from premium Purple Copper with corrosion-resistant tin plating for maximum conductivity. These high-purity terminals prevent wire strands from fraying or breaking, ensuring long-lasting electrical safety and superior performance compared to standard brass alternatives.
PRECISION 4-SIDE SQUARE CRIMP: The classic quadrilateral ratchet mechanism creates a high-pressure, uniform square crimp with a massive contact surface area. Specially designed for AWG 28-7 (0.08-10mm²), it ensures maximum electrical conductivity and the rock-solid connection required for heavy-duty professional wiring.
ERGONOMIC & LABOR-SAVING DESIGN: Engineered with non-slip handles and a quick-release safety lever to significantly reduce hand fatigue. The self-adjusting tool automatically adapts to the appropriate diameter for terminals within the AWG 28-7 range, making it ideal for both complex industrial panels and intricate DIY projects.
PROTECTIVE INSULATION & ORGANIZED STORAGE: The flared insulated sleeves offer enhanced arc protection and easier wire insertion, making them essential for high-density junction boxes and vibration-prone automotive or marine wiring. Comes in a durable, labeled case for rapid identification and professional organization.
