The OnGuard Mastiff 4 ft. Key Chain Lock provides dependable everyday protection for bicycles, e-bikes, scooters, and outdoor equipment. The 120 cm (4 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, AOS X2P Dual Lock Down mechanism, securing both sides of the shackle to improve resistance against pulling and prying attempts. A 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 weather exposure. An automatic keyway cover helps block dust and moisture from entering the lock cylinder for reliable long-term operation. Includes 5 precision laser-cut keys.
