Trusted by thousands, it’s the essential upgrade to safeguard your trailer and accessories from theft while ensuring effortless operation. ## Description Make your tow vehicle and trailer more secure by keeping them locked up tight with a CURT hitch lock. Like a hitch pin and clip, a hitch lock is designed to insert into the fastener hole in the side of a receiver tube in order to hold a ball mount or hitch-mounted accessory in place. While a CURT hitch pin does offer sufficient strength for keeping your ball mount firmly attached, a CURT hitch lock goes one step further. CURT hitch locks allow you to lock your ball mount into your trailer hitch, deterring theft and preventing anyone from detaching your trailer at the ball mount and towing away your property without your permission. This CURT hitch lock features a barbell design and comes with a 5/8" pin diameter to fit a 2" receiver tube size (usable pin length is 2.850"; will not work with double-walled receiver tubes). CURT barbell hitch locks are comprised of a pin with two end caps and a round locking mechanism. They are key-operated and activate with a simple 1/4-turn. They also come with a watertight dust cap to keep out the elements and prevent corrosion. For the ultimate in towing security, a hitch lock and coupler lock used together will provide security at both the vehicle-side and trailer-side of your towing setup. For your boat, ATV or camper, keep your toys more secure with CURT hitch locks. Review: Fits perfect - Nice product, fits perfect Review: Easy to use - Works great. ## Features - DEPENDABLE SECURITY.

No signs of rust or fading from being outside all the time. The rubber cap can go missing fairly easy if you're not careful. These types of locks aren't unbreakable, but it does help deter theft, because rather than removing a pin without any tools and taking your hitch, a thief would at least have to commit to breaking the pin. A step many wouldn't bother doing especially in a public space. Cheap, easy to use peace of mind. ## Frequently Bought Together - CURT 23518 Black Trailer Hitch Lock, 5/8-Inch Pin Diameter, Fits 2-Inch Receiver - Rhino USA Hitch Tightener Anti Rattle Clamp (for 2 inch Hitches) Heavy Duty Steel Trailer Hitch Stabilizer - Weatherproof Protective Anti-Rust Silencer for Bike Rack, Hitch Receiver & More! - Mission Automotive 3 Pack Silencer Pads for 2 Inch Ball Mounts - Reduces Rattle and Noise Between Receivers and Tow - Fits Any Trailer Hitch Receiver - Trailer Hitch Stabilizer Silencer Pad --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/16745041-curt-23518-5-8-barbell-hitch-lock-for-2-receivers](https://www.desertcart.us/products/16745041-curt-23518-5-8-barbell-hitch-lock-for-2-receivers) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-05*
