Compact shackle design paired with an expansive opening, delivering straightforward security for general-purpose applications.
The SAS KB21 Unilock Padlock is a special‑purpose shackle lock designed for versatile applications. With its large opening and unusually small shackle diameter, it fits where other padlocks cannot, making it ideal for securing a wide range of equipment.
Built with a solid brass lock body for durability, the KB21 features an enclosed hardened chrome‑plated steel shackle for increased strength. A high‑precision 6‑pin brass lock and cylinder core ensure smooth operation, while three nickel‑plated brass keys are supplied as standard. The padlock is also available keyed alike for added convenience.
Specifically designed to fit a Knott pressed steel trailer hitch with a curved handle and through‑hole, the KB21 locks the hitch handle securely, enabling you to lock the trailer to the towing vehicle.
