Product Summary

Protect your trailer with confidence using the TRIMAX UMAX300SM, a fully-shrouded heavy-duty universal coupler lock engineered for serious theft deterrence. Built with a rugged die-cast body and hardened steel shackle, this lock delivers 360° protection for unattended trailers, RVs, boats, and utility haulers. Designed to fit virtually all standard coupler sizes (1-7/8”, 2”, and 2-5/16”), the UMAX300 features a patented dual ratchet locking system that secures tightly and resists forced entry. A reinforced design helps deflect hammer strikes, while the corrosion-resistant hammer-tone finish ensures long-term durability in harsh outdoor conditions. The integrated keyhole cover helps keep dirt, moisture, and debris out of the locking mechanism, maintaining smooth operation over time. Paired with a high-security tubular key system, the UMAX300SM is built for dependable everyday use and long-term trailer protection. Whether parked at a job site, storage lot, or campsite, the TRIMAX UMAX300SM helps ensure your trailer stays exactly where you left it.
