Designed to fit 1-7/8”, 2” and 2-5/16” couplers, the CURT universal heavy-duty trailer coupler lock gives you the peace of mind you need when heading out for a weekend getaway or securing your trailer in the driveway. Its innovative ratchet-style mechanism makes securing your trailer a breeze. 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 easy — turn the key a quarter turn, and you’re good to go. The U-lock’s inside width of 3-7/8" accommodates most trailers with ease, while the innovative ratchet locking system provides 10 locking positions for a precise fit that makes cutting the lock extremely difficult. This heavy-duty coupler lock is built tough with a heavy-duty steel locking bar and aluminum body that’s not only weather-resistant but nearly impenetrable. Its advanced design stops theft and unwanted hookups by preventing a trailer ball from being inserted into the coupler. Plus, its heavy-duty locking cylinder adds another layer of security and ensures your trailer remains exactly where you left it. Last but certainly not least, its bright orange powder coat finish will deter thieves and keep them from tampering with your trailer. Whether you’re heading out for a fishing trip at your favorite hot spot or simply securing your trailer in the backyard, the CURT universal heavy-duty coupler lock is a must-have for trailer security. With its blend of rugged protection, ease of use, and high-visibility deterrence, it’s the smart, dependable choice for any trailer owner.
