Mastiff 6' Chain with Integrated Key Lock

The OnGuard Mastiff 6' Chain with Integrated Key Lock delivers maximum protection for high-theft areas using a 1725 mm (68 in) titanium-reinforced hardened-steel square-link chain. The integrated X2P Dual Lock Down mechanism secures both sides of the shackle for superior resistance to pulling, cutting, and leverage attacks. A co-molded lock body and metal endcaps provide additional impact protection, while the automatic keyway cover keeps dirt and moisture out for long-term reliability. Includes five precision laser-cut keys—one with an LED light—and OnGuard’s anti-theft protection plan for added peace of mind.
