The OnGuard Mastiff 2.6 ft Chain Lock delivers compact, high-strength protection for bicycles, e-bikes, scooters, and outdoor equipment. The 80 cm (2.59 ft) chain uses titanium-reinforced hardened-steel square links engineered to resist cutting, twisting, and leverage attacks in urban environments. Its integrated lock head features OnGuard’s X2P Dual Lock Down mechanism, securing both sides of the shackle to improve resistance against pulling and prying attempts. A durable double rubber-coated lock body helps absorb impacts and protect finishes, while the protective sleeve helps prevent scratches and shields the chain from corrosion and outdoor wear. An automatic keyway cover helps keep dust and moisture out of the cylinder for reliable long-term performance. Includes five precision laser-cut keys.
