MASTIFF Series Bicycle and Powersport Security Chain Designed for high-security needs, the MASTIFF series features slightly smaller, squared links compared to the BEAST chains, providing ultimate protection for bicycles and powersport equipment in high-crime areas. The oversized, titanium-reinforced hexagonal links make hacksaws and bolt cutters almost ineffective, while the tight inside link dimensions prevent prying. Available in various chain lengths and link sizes to suit your security requirements, this 3.5-foot rugged chain with a Boxer U-Lock offers superior durability. The hexagonal and square links offer more hardened surfaces than round links, making sawing and cutting nearly impossible. Titanium surface hardening significantly enhances cut and saw resistance. The embroidered nylon chain covers prevent cracking or peeling, ensuring long-lasting appearance, while Velcro tabs keep covers securely in place to protect your paint and finishes. Choose from a comprehensive selection of lock types, chain lengths, and link sizes to perfectly match your security needs.
