Overview

The Trimax Locks UMAX300SM is a shrouded coupler lock designed for trailer security. It features a 7/8-inch hardened steel dual-locking HEX shackle and a 5mm weather-resistant powder-coated shroud that provides 360-degree protection. The lock body is constructed from solid die-cast material to absorb hammer blows and offers a rust-proof finish. A keyhole cover protects the lock mechanism from dirt and grime.
