Description
Park your trailer with peace of mind. The Master Lock 605DAT Trailer Coupler Lock drops into a 2 in coupler ball socket and locks it shut — no thief can lift the latch and roll your trailer away. The brass body and 3/4 in shackle resist rust and corrosion through years of outdoor exposure, and the keyed mechanism stays smooth even after a winter sitting in a snowbank.
Why Trailer Owners Pick This Lock
- Fits standard 2 in coupler ball sockets — the most common size on utility, boat, and small enclosed trailers
- Solid brass body resists rust and corrosion in outdoor and marine environments
- 3/4 in (19 mm) hardened-steel shackle bites back against bolt cutters and pry attacks
- Drops into the latch position when the coupler is open — no separate bracket to install
- Includes two keys with a unique key code — replacements available through Master Lock
- Weather-resistant cylinder stays smooth in rain, snow, and freeze-thaw cycles
Where It Shines
- Utility, landscape, and contractor trailers parked overnight on jobsites
- Boat trailers at marina lots and ramps
- RV and travel-trailer storage between trips
- Cargo trailers in driveways and storage yards
