Universal Heavy-Duty Trailer Coupler Lock #23091

The CURT universal heavy-duty trailer coupler lock is designed to fit 1-7/8”, 2”, and 2-5/16” couplers, offering reliable security whether you’re heading out for a weekend getaway or securing your trailer in the driveway.

Featuring an innovative ratchet-style mechanism, this lock makes securing your trailer straightforward. Simply insert the lock base into the coupler, slide the U-bar over the coupler’s nose, and lock it in place. Unlocking is just as simple—turn the key a quarter turn to release. With an inside width of 3-7/8", the U-lock fits most trailers effortlessly, and its ratchet locking system provides 10 positions for a precise fit, making it extremely difficult to cut.

Built tough, the coupler lock has a heavy-duty steel locking bar and an aluminum body that are both weather-resistant and nearly impenetrable. Its advanced design prevents theft and unauthorized hookups by blocking the trailer ball from being inserted into the coupler. Additionally, the heavy-duty locking cylinder adds an extra layer of security, ensuring your trailer stays put.

Whether you're off to your favorite fishing spot or simply securing your trailer in the backyard, the CURT universal heavy-duty coupler lock offers a blend of rugged protection, ease of use, and high-visibility deterrence. It’s the smart and reliable choice for any trailer owner.
