Take Control Of Towing With Built In Security

If you’re looking for a lunette ring that works harder to protect your trailer and simplify your hookup, the CURT SecureLatch 48661 delivers exactly what you need. This flush-mount lunette ring is built with real-world use in mind, starting with its integrated locking pin. Whether you’re parked overnight at a jobsite or running errands mid-haul, the locking pin drops down and helps prevent unwanted coupling and theft. And when it's time to hook up, that same pin rotates out of the way in seconds, letting you hitch up and get moving without hassle. The offset base gives you more flexibility too, letting you flip the ring for extra rise or drop to dial in the perfect height. Whether you're towing with a work truck or hauling equipment cross country, this ring keeps things level and locked in. It’s a simple upgrade that adds serious peace of mind.

Built To Withstand Heavy Loads And Harsh Conditions

The CURT 48661 SecureLatch Lunette Ring is engineered to handle demanding trailers and rough towing environments with confidence. Constructed from heavy-duty cast iron and treated with an austempering process, this lunette ring is built for extreme durability and enhanced wear resistance over time. It’s rated to handle up to 60,000 pounds of gross trailer weight, making it a strong choice for commercial, agricultural, or industrial applications. The flush-mount design features bolt holes spaced 4.5 inches apart both vertically and horizontally for a secure fit, and hardware is included for easy installation. With a 2.5 inch inside ring diameter, it pairs seamlessly with pintle hooks, ball and pintle combos, or clevis hitches. The integrated locking pin is more than just a security feature, it also helps streamline your towing setup by staying out of the way when not needed. Finished in a premium dark grey teridium powder coat, this ring is built to resist corrosion and perform reliably through years of heavy-duty use.
