Our locks provide a snug fit on your trailer coupler, installing in ten seconds with one hand and laughing off hammers, pry bars, saws, and even grinders. Thick solid ¼″ steel housing, a fully enclosed ¾″ locking pin, and parts that interlock so nothing to lose or misplace.

One Piece Construction

Housing is formed and welded to create a one-piece housing component – no hinges to seize or be tampered with. That means you’ll never wrestle with loose parts or binding joints when you need protection—just rock-solid reliability, 365 days a year.
