Comes with two keys for added convenience, making it the essential upgrade for protecting your trailer and accessories. ## 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: Works as advertised, protected my hitch. - I was pleased with the weight and durability of this lock, and I guess I'll have to order another one. I found that someone tried to make off with my B&W hitch by attempting to break this pin but wasn't able to. Unfortunately the key no longer worked and I had to shear it off but props to Curt for making a great hitch lock! ## Features - DEPENDABLE SECURITY. To protect your trailer and trailer hitch ball mount from theft, this locking hitch pin is made with high-strength steel construction - EASY TO OPERATE.

With a 5/8-inch diameter pin and 2.85 inches of usable pin length, this receiver hitch lock fits virtually any 2-inch x 2-inch hitch receiver with a 5/8-inch hole (not compatible with double-walled receiver tubes) - WATERTIGHT.
