Drop-Forged High-Carbon Steel Mobile Jaw: Heavy-duty forged hook jaw provides superior structural tensile strength, ensuring deep-biting grip and long tooth life under high torque.
Corrosion-Resistant Inactivate Surface Treatment: Specialized passivation finish forms an anti-corrosion barrier that protects components against moisture, plumbing leaks, and rust.
Reinforced Solid Rivet Pivot Construction: Heavy-duty solid steel rivet assembly maintains strict jaw alignment and prevents head displacement during extreme rotational leverage.
Wide Clamping Range (40mm to 85mm): Full size spectrum accommodates diverse plumbing schedules, fitting threaded steel pipe, sanitary brass collars, and large civil water mains.
Ergonomic High-Torque I-Beam Handle: Contoured cast handle geometry ensures balanced load distribution, preventing hand strain and handle deflection across demanding job sites in Nepal.
