Home / Product Line / UCS-82A



Keep your cargo safe with the patent-pending UCS-82A, the most innovative lock in trailer security. The UCS-82A is built to secure container doors on virtually all intermodal containers. The UCS-82A keeps your cargo safe with its hidden shackle, enclosing the shackle beneath the body of the lock. This cutting-edge design keeps the shackle concealed and the lock impervious to bolt cutter and hacksaws. With all aluminum, stainless steel, and brass components, this lock is built to last.

Because PACLOCK uses all stainless steel and brass components in its locks, PACLOCK padlocks continue to work after years of exposure to harsh conditions such as crossing the sea or traveling on trains.

All PACLOCK padlocks come standard with 6-pin cylinder technology.  padlocks only have 4-pins, leaving them relatively easy to pick and making duplicate key combinations a problem. Our standard 6-pin cylinder far exceeds the U.S. military lock requirements of a 5-pin cylinder. The insides of our locks are built using brass, aluminum, and stainless steel components, keeping them secure from not just unwanted guests, but harsh weather as well.

Along with being truly secure and having long-lasting durability, PACLOCK’S Universal Cylinder System padlocks can be keyed-alike, master-keyed, and even grand-master-keyed to minimize the number of keys you need to carry around.
