The Umax 100 is the "Big Daddy" of the universal couple locks. While no lock is invincible, the Trimax Umax 100 will take a beating, literally, and keep your trailer safe.
With a 5/8" hardened steel shackle above and solid steel pins, surrounded by a steel casing underneath the plastic housing below, the Umax 100 is one tough lock.
