With the highest rating on our PACLOCK security scale, it doesn’t just keep people out—it keeps them from thinking about stealing your stuff in the first place. The body of the padlock is precision-machines from 6061 aircraft-grade aluminum offering exceptional resistance to grinder attacks by clogging the blades. For added protection, the padlock incorporates a 304 stainless steel pin in the shroud, creating an additional barrier against cutting. Built to withstand the most rigorous security challenges, the “UCS-17A-1100” seamlessly integrates with two ends of PACLOCK’s 1/2” square chain, securing the shackle from cutting and prying attacks. This kit includes 6-feet of PACLOCK’s 1/2” hardened steel square link chain. This heavy-duty chain is specifically designed to resist cutting, sawing, and other physical attacks. Its square-link design makes it extremely difficult for bolt cutters to gain the leverage needed for a clean cut, adding another layer of defense. With it’s zinc plating and hardness rating of 62 HRC, the chain offers industry-leading durability and corrosion resistance, making it ideal for both indoor and outdoor use. Whether you’re securing trailer wheels, motor bikes, or industrial gates, this chain is built to handle the toughest conditions.
